Pulsar planet

I've listed this article for peer review because I wanted to see if it stands a chance as a GA candidate.

Thanks, Jo-Jo Eumerus (talk) 16:44, 26 July 2023 (UTC)

will look though the article, pls expect comments in the next few days. Artem.G (talk) 14:12, 4 August 2023 (UTC)

Comments from Artem.

I'm not an astronomer, so some comments can be quite stupid.

• They are extremely rare - can it be the case that our current technology doesn't allow to detect them? maybe not rare, but hard to detect?

  Yeah, there are limitations in viewing them but even among the pulsars where detection is easy, there aren't many. Jo-Jo Eumerus (talk) 16:25, 8 August 2023 (UTC)

• with only half a dozen listed by the NASA Exoplanet Archive. - why not say "only seven listed"?

  Only because I think this warrants a rough number not a precise one. Jo-Jo Eumerus (talk) 16:25, 8 August 2023 (UTC)

• Thus, a disk needs to have a large mass if it is to give rise to planets. - is it different from any other planets? shouldn't protoplanetary disk of any star be massive to form a planet? if no, then the definition of "large mass" is needed.

  Source doesn't seem to specify. Jo-Jo Eumerus (talk) 16:25, 8 August 2023 (UTC)

• I would move the text from note a to the actual text.

  I am hearing you, but I don't think there is a good place for this. Jo-Jo Eumerus (talk) 16:25, 8 August 2023 (UTC)

• you have "First generation" planets but then "Second generation planets" and "Third generation planets", I think quotes should be consistent.

  Done. Jo-Jo Eumerus (talk) 16:25, 8 August 2023 (UTC)

• about the first gen - None of the known pulsar planet systems are likely to have formed in this process., about the second gen - There are no known examples of planets around young neutron stars.. There is nothing about three other types. What types are the identified planets?

  There are a few examples, but it's already discussed in a separate section, not sure we want to mention them twice. Jo-Jo Eumerus (talk) 16:25, 8 August 2023 (UTC)

• The formation scenarios have consequences for the planets' composition: A planet formed ... - I would put a period instead of a colon, but I'm not a native speaker, so you can ignore it.

  Me neither, I admit

• As of 2022, the most common type of neutron star planet is a "diamond planet" - how is it related to 5 types discussed above?

  It's most commonly a third-generation pulsar planet. Jo-Jo Eumerus (talk) 16:25, 8 August 2023 (UTC)

• Pulsars are extremely precise clocks - maybe Pulsars can serve as an extremely precise clocks?

  Hrm, I don't think these are the same statement. Jo-Jo Eumerus (talk) 16:25, 8 August 2023 (UTC)

• the least massive known extrasolar planet (only 0.02 MEarth) is a pulsar planet - is there a name for it, or an article?

  Yep, linked. Jo-Jo Eumerus (talk) 16:25, 8 August 2023 (UTC)

• Pulsars are very small and thus the probability of a planet transiting in front of the pulsar - one potential way to image them - is very low. - I think it can better be said as One potential way to image a planet is to detect its transition in front of the star: in case of pulsar planets, the probability of a planet transiting in front of pulsar is very low because of the small size of pulsars., or smth like that.

  That works; I've put it in. Jo-Jo Eumerus (talk) 16:25, 8 August 2023 (UTC)

  • that relates to the They are extremely rare - maybe we just can't detect them?
    • Problem is that different techniques should reliably detect pulsar planets. Jo-Jo Eumerus (talk) 16:25, 8 August 2023 (UTC)
• As of 2022 only half a dozen[c] - same comment as above - if you decided to stick to The NASA Exoplanet Archive, just say "seven planets"

  Put an "about" in. Jo-Jo Eumerus (talk) 16:25, 8 August 2023 (UTC)

• Based on the known occurrence rate of pulsar planets, there might be as many as 10 millions of them in the Milky Way.[41] - again, I don't think it's "extremely rare" - maybe some comparison with ordinary planets can be useful here?

  Done. Jo-Jo Eumerus (talk) 16:25, 8 August 2023 (UTC)

• Examples - you don't need additional indentation there, each example has only one paragraph

  Done. Jo-Jo Eumerus (talk) 16:25, 8 August 2023 (UTC)

• described as a "diamond planet". - diamond planet is a better link

  Done. Jo-Jo Eumerus (talk) 16:25, 8 August 2023 (UTC)

• The parameters of known pulsar planetary system - if there is no data about Inclination and Radius, maybe this columns are not needed (at least right now)?

  I don't think I can hide this parameter, no. Jo-Jo Eumerus (talk) 16:25, 8 August 2023 (UTC)

• of an asteroid[h] belt around the pulsars - move note after the "belt", and maybe link to asteroid belt

  Done. Jo-Jo Eumerus (talk) 16:25, 8 August 2023 (UTC)

• The white dwarf-pulsar binary - "dwarf-pulsar" puzzles me, but it's probably correct

  Yeah, "white dwarf" and "pulsar" are supposed to be separate. Jo-Jo Eumerus (talk) 16:25, 8 August 2023 (UTC)

• See also - first link is used above, and you can link exoplanet in text. for the Aleksander Wolszczan and Dale Frail, you can add a sentence to the pulsar they've discovered and remove links from see also. Same for Andrew Lyne, if possible.

  Mostly done. Jo-Jo Eumerus (talk) 16:25, 8 August 2023 (UTC)

These are all comments I have, hope they're useful. Article looks good to be submitted to GA - sources are good, and for such an obscure topic it looks solid. Artem.G (talk) 15:29, 8 August 2023 (UTC)

I read the aricle once again, and the only comment I have now is that some comparison of pulsar planets or pulsar planetery systems to Earth or to the Solar System can be useful. I don't know how reliable are these images, but they look quite illustrative: File:Exoplanet_Comparison_PSR_B1257+12_C.png, File:Exoplanet_Comparison_PSR_B1257+12_A.png. Artem.G (talk) 12:31, 12 August 2023 (UTC)

Hrmm, these are of two specific exoplanets and only about their size; I don't think that works. Jo-Jo Eumerus (talk) 18:25, 12 August 2023 (UTC)
