The Initial Mass Function Based on the Full-sky 20-pc Census of 3,600 Stars and Brown Dwarfs
J. Davy Kirkpatrick, Federico Marocco, Christopher R. Gelino +85
A complete accounting of nearby objects -- from the highest-mass white dwarf progenitors down to low-mass brown dwarfs -- is now possible, thanks to an almost complete set of trigo…
Main sequence companions to white dwarfs II: the age-activity-rotation relation from a sample of Gaia common proper motion pairs
A. Rebassa-Mansergas, J. Maldonado, R. Raddi +8
Magnetic activity and rotation are related to the age of low-mass main sequence stars. To further constrain these relations, we study a sample of 574 main sequence stars members of…
The unusual planetary nebula nucleus in the Galactic open cluster M37 and six further hot white dwarf candidates
Klaus Werner, Nicole Reindl, Roberto Raddi +6
Planetary nebulae in Galactic open star clusters are rare objects; only three are known to date. They are of particular interest because their distance can be determined with high…
White dwarf spectral type-temperature distribution from Gaia-DR3 and the Virtual Observatory
S. Torres, P. Cruz, R. Murillo-Ojeda +6
The characterization of white dwarf atmospheres is crucial for accurately deriving stellar parameters such as effective temperature, mass, and age. We aim to classify the populatio…
Carbon-oxygen ultra-massive white dwarfs in general relativity
Leandro G. Althaus, Alejandro H. Córsico, María E. Camisassa +4
We employ the La Plata stellar evolution code, LPCODE, to compute the first set of constant rest-mass carbon-oxygen ultra-massive white dwarf evolutionary sequences for masses high…
A hidden population of white dwarfs with atmospheric carbon traces in the Gaia bifurcation
Maria Camisassa, Santiago Torres, Mark Hollands +4
The ESA Gaia space mission has revealed a bifurcation of the white dwarf (WD) sequence on the color magnitude diagram in two branches: A and B. While the A branch consists mostly o…
