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. - 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
- maybePulsars 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 asOne 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?- Examples - you don't need additional indentation there, each example has only one paragraph
described as a "diamond planet".
- diamond planet is a better link- 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 beltThe 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.

- 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)
