    Top three smallest non-degenerate stars| 1.NGC 2867 Central Star / 0.05 SR (Tiny little Wolf-Rayet Star) 2.NGC 4361 Central Star / 0.061 SR (Another Tiny little Wolf-Rayet Star) 3.TMTS J052610.43+593445.1 A / 0.066 SR (little Blue Subdwarf)

      The central star of NGC 5189 is even smaller, at 0.03 SR. Also, CSPN (central star of planetary nebula) stars are usually not considered WR stars.

    Nice
    At 1:29 Pretty sure the TMTS star is a subdwarf B type, not a white dwarf. The largest white dwarf is Z Andromedae B, at between 236,000 and 501,000 km.
    Kepler-1520 b should be much smaller, probably around Mercury sized.
    If you list the size for 54 Piscium B, you should call it that instead of 54 Piscium A b.
    Also yay for Saturn and Jupiter!

      About TMTS, THEY LITERALLY CHANGED THAT SHORTLY AGO... (In Wikipedia Smallest Stars list they even kept the "Smallest Non-Degenerate Star" Title)
      About Z Andromedae B, that is also a Subdwarf.
      And yes, Kepler-1520 b should be smaller...

      Z Andromedae B is not a subdwarf, in fact it is a white dwarf it says that in the first line in the Wikipedia article of Z Andromedae.

    4:47 I think it was removed due to not being in the paper at all, I wasn't able to find it and SIMBAD doesn't show a paper matching wikipedia's reference on the page for that star. The EBLM star is more reasonable to be the smallest red dwarf and main sequence star.

    • @JLTruRodYT
      @JLTruRodYT  7 місяців тому

      Actually, that Star is on SIMBAD: simbad.cds.unistra.fr/simbad/sim-id?Ident=SSSPM+J2356-3426&submit=submit+id
