Cataclysmic Variables Photometric Periods from TESS
S. O. Kepler, Alejandra Daniela Romero, Larissa Luciano Amorim +1
We present a sample of coherent and stable photometric period determinations for cataclysmic variables, based on TESS photometry through sector 102. We analyzed a total of 1554 cat…
White Dwarf Classification of DESI DR1 Spectra1
Larissa L. Amorim, Weligton. N. Costa Junior, S. O. Kepler +3
We present a new catalog of spectroscopically confirmed white dwarfs from the Dark Energy Spectroscopic Instrument (DESI) Data Release 1. We visually classified 44,417 white dwarf…
Magnetic white dwarfs from DESI
Larissa L. Amorim, S. O. Kepler, Alejandra D. Romero
A significant fraction of white dwarfs, the degenerate remnants of low- and intermediate-mass stars, host strong magnetic fields; yet, the origin and evolution of these magnetic fi…
Evolution and formation of ultramassive white dwarf stars: The case for a 9Msun progenitor
Ana S. R. Antonini, Alejandra D. Romero, S. O. Kepler
We study the full evolution of a 1.313 Msun white dwarf star that descended from a 9 Msun main-sequence progenitor with an initial metallicity of Z=0.02. Using MESA r24.08.01, we c…
