Asteroseismological analysis of the polluted ZZ Ceti star G29-38 with TESS

Murat Uzundag, Francisco C. De Gerónimo, Alejandro H. Córsico +15

G\,29 $-$ 38 (TIC~422526868) is one of the brightest ( $V = 13.1$ ) and closest ( $d = 17.51$ \,pc) pulsating white dwarfs with a hydrogen-rich atmosphere (DAV/ZZ Ceti class). It was obser…

WD J004917.14 $-$ 252556.81, the Most Massive Pulsating White Dwarf

Mukremin Kilic, Alejandro H. Córsico, Adam G. Moss +3

We present APO and Gemini time-series photometry of WD J004917.14 $-$ 252556.81, an ultramassive DA white dwarf with $T_{eff} = 13020$ K and $lo g g = 9.34$ . We detect variabili…

Uncertainties in the 12C+12C reaction rate and their impact on the composition of ultra-massive WDs

F. C. De Gerónimo, M. M. Miller Bertolami, M. Catelan +1

Stars with initial masses 7 Msun . MZAMS . 9 Msun reach temperatures high enough to ignite C under degenerate conditions after the end of He-core burning (Garcia-Berro & Iben 1994)…
