Notability

[The following was posted by the draft's author on my Talk page and I am copying it here for greater visibility and convenience--Cabrils]

Hi. Thank you for reviewing my draft and thank you for providing a detailed assessment of the issues. I have edited the article based on your feedback.

1. He meets criteria 1 of WP:NPROF. According to Google Scholar, his working has been cited over 24,000 times and he has an h-index of 81. According to Scopus, his work has a citation count of over 15000 and an h-index of 61. I have now added this information to the article.

2. I have removed information I felt was excessive detail and made the article read like a CV. I have only left information about his primary appointments and a chairmanship to an important working group.

3. I have declared my COI on my user page, and not on my talk page based on this guideline. I can add the same information to my talk page as well if both are necessary. Please let me know. I understand that my paid status makes me biased and oblivious to errors in the article so I am completely open to your feedback. Thank you for providing very detailed and concrete feedback while declining the article. HRShami (talk) 05:40, 19 December 2025 (UTC)[reply]

@HRShami, thanks for this information.

On balance I agree the draft is "unlikely to be deleted in mainspace" (see WP:AFCR), and meets WP:NPROF. Accepted into mainspace. Cabrils (talk) 04:28, 23 December 2025 (UTC)[reply]

Comments left by AfC reviewers

• Comment: Well done on creating the draft, and it may potentially meet the relevant requirements (including WP:GNG, WP:ANYBIO, WP:NPROF) but presently it is not clear that it does.
  As other reviewers have noted, Wikipedia's basic requirement for entry is that the subject is notable. Essentially subjects are presumed notable if they have received significant coverage in multiple published secondary sources that are reliable, intellectually independent of each other, and independent of the subject. To properly create such a draft page, please see the articles ‘Your First Article’, ‘Referencing for Beginners’ and ‘Easier Referencing for Beginners’. In short, "notability" requires reliable sources about the subject, rather than by the subject.
  The image used likely breaches copyright, which Wikipedia takes seriously, so should be removed unless clear evidence of its legal use is provided. If it is indeed the draft's author's "Own work" then the author clearly knows the subject and has a conflict of interest that must be declared (see details below). It seems highly unlikely that it is /they are the draft's author's "Own work", unless the author is also a professional photographer, but no such evidence has been provided.
  Additionally, the draft tends to read too much like a promotional CV (see WP:PROMO and WP:EXCESSDETAIL), which Wikipedia is not.
  Thank you for declaring your conflict of interest. Please note that if you have not already done so, you must also declare your COI on your Talk page (to see instructions on how to do this please click the link). Given the conflict, the review of the page needs to be handled with care, mindful of the higher bar set by pages produced in circumstances of conflict of interest. Such pages typically may read too much like a promotional CV or advertorial (see WP:PROMO), which Wikipedia is not; and/or contain prose that is not of a standard appropriate for an encyclopaedia (also see WP:PEACOCK and WP:NPV).
  Please familiarise yourself with these pages before amending the draft. If you feel you can meet these requirements, then please make the necessary amendments before resubmitting the page.
  It would help our volunteer reviewers by identifying, on the draft's talk page, the WP:THREE best sources that establish notability of the subject.
  It would also be helpful if you could please identify with specificity, exactly which criteria you believe the page meets (eg "I think the page now meets WP:NPROF criteria #3, because XXXXX").
  Once you have implemented these suggestions, you may also wish to leave a note for me on my talk page, including the name of the draft page, and I would be happy to reassess. As I said, I do think this draft has potential so please do persevere. Cabrils (talk) 01:53, 19 December 2025 (UTC)[reply]

• Comment: Hi Ldm1954. Thank you for reviewing my draft. His birthdate is mentioned in his CV. I have now added it as a reference to birthdate. I have added some secondary sources to confirm dates in his career and education. I did not add awards because while he has received many, none of them are verifiable through the awarding body's website or a third party source. He hasn't had any important editorship. However, he was chair of the IAU Working Group on Star Names, which I have added now.HRShami (talk)

• Comment: This is quite unbalanced. You have no reference for his birth and high school, and only his CV for his education and career. Then you have 14 references where his research is mentioned. These are not resumes, they should be encyclopedic information. What about awards? What about editorial roles? Please downplay the research and add encyclopedic information with independent sourcing. Ldm1954 (talk) 23:45, 8 December 2025 (UTC)[reply]

• Comment: In accordance with the Wikimedia Foundation's Terms of Use, I disclose that I have been paid by my employer for my contributions to this article. HRShami (talk) 05:29, 8 December 2025 (UTC)[reply]

Research section

The user below has a request that an edit be made to Eric Mamajek. That user has an actual or apparent conflict of interest. The requested edits backlog is very high. Please be extremely patient. There are currently 336 requests waiting for review. Please read the instructions for the parameters used by this template for accepting and declining them, and review the request below and make the edit if it is well sourced, neutral, and follows other Wikipedia guidelines and policies.

Please replace the second paragraph of the research section with the paragraph below. I have added some more information sourced from reliable news websites to add the primary sources tag on the article.

Mamajek is the [[eponym]] of "Mamajek's Law" for the increasing discovery rate of exoplanets, and is the co-discoverer of the ringed [[substellar object]] [[J1407b]], which has sometimes been called "Mamajek's Object". A focus of his research work lies in calibrating and applying age-dating techniques for stars and young stellar groups. Similarly, he has investigated young open clusters and stellar associations and utilized [[Bayesian inference]] to calculate membership probability for 29 stellar associations within 150 parsecs of the Sun. His work has also explored the [[Scholz's star]]'s Sun encounter. In collaboration with Stapelfeldt, he has documented the list of nearby stars which will be the best target stars for the future NASA [[Habitable Worlds Observatory]] to search for potentially habitable worlds.

Mamajek is the [[eponym]] of "Mamajek's Law," describing the increasing discovery rate of exoplanets, and is the co-discoverer of the ringed [[substellar object]] [[J1407b]], which has sometimes been called "Mamajek's Object". The object is notable for an extensive ring system inferred from complex eclipses of its host star, with ring structures far larger than those of Saturn and exhibiting gaps that may indicate ongoing satellite formation. A focus of his research work lies in calibrating and applying age-dating techniques for stars and young stellar groups. Similarly, he has investigated young open clusters and stellar associations and utilized [[Bayesian inference]] to calculate membership probability for 29 stellar associations within 150 parsecs of the Sun. In addition, Mamajek led research showing that the nearby binary system known as [[Scholz's Star]] passed through the outer Oort Cloud approximately 70,000 years ago, representing the closest known stellar flyby of the Solar System and highlighting the frequency of such encounters.
