White dwarf and subdwarf stars in the Sloan Digital Sky Survey Data Release 16

S. O. Kepler, Detlev Koester, Ingrid Pelisoli +2

White dwarfs are the end state of the evolution of more than 97% of all stars, and therefore carry information on the structure and evolution of the Galaxy through their luminosity…

Evidence of Spectral Evolution on the white dwarf sample from the Gaia Mission

G. Ourique, S. O. Kepler, A. D. Romero +2

Since the Gaia data release 2, several works were published describing a bifurcation in the observed white dwarf colourmagnitude diagram for $\mbox{$G_{\mathrm{BP}}$}-\mbox{$G_{…

Ground based observation of ZZ Ceti stars and the discovery of four new variables

Alejandra D. Romero, L. Antunes Amaral, T. Klippel +7

We perform ground based photometric observations of 22 DA white dwarf stars, 10 already known ZZ Cetis and 12 candidates with atmospheric parameters inside the classical instabilit…

White dwarf and subdwarf stars in the Sloan Digital Sky Survey Data Release 14

S. O. Kepler, Ingrid Pelisoli, Detlev Koester +6

White dwarfs carry information on the structure and evolution of the Galaxy, especially through their luminosity function and initial-to-final mass relation. Very cool white dwarfs…

A Study of Cool White Dwarfs in the Sloan Digital Sky Survey Data Release 12

G. Ourique, A. D. Romero, S. O. Kepler +2

In this work we study white dwarfs where to compare the differences in the cooling of DAs and non-DAs and their f…

White Dwarf Stars

S. O. Kepler, Alejandra Daniela Romero, Ingrid Pelisoli +1

White dwarf stars are the final stage of most stars, born single or in multiple systems. We discuss the identification, magnetic fields, and mass distribution for white dwarfs dete…

White Dwarf Mass Distribution

S. O. Kepler, Detlev Koester, Alejandra Daniela Romero +2

We present the mass distribution for all S/N > 15 pure DA white dwarfs detected in the Sloan Digital Sky Survey up to Data Release 12, fitted with Koester models for ML2/alpha=0.8,…

New white dwarf and subdwarf stars in the Sloan Digital Sky Survey Data Release 12

S. O. Kepler, Ingrid Pelisoli, Detlev Koester +7

We report the discovery of 6576 new spectroscopically confirmed white dwarf and subdwarf stars in the Sloan Digital Sky Survey Data Release 12. We obtain Teff, log g and mass for h…

New white dwarf stars in the Sloan Digital Sky Survey Data Release 10

S. O. Kepler, Ingrid Pelisoli, Detlev Koester +11

We report the discovery of 9 089 new spectroscopically confirmed white dwarfs and subdwarfs in the Sloan Digital Sky Survey Data Release 10. We obtain Teff, log g and mass for hydr…
