Accurate mass-radius ratios for Hyades white dwarfs
L. Pasquini, A. F. Pala, M. Salaris +4
We use the ESPRESSO spectrograph at the Very Large Telescope to measure velocity shifts and gravitational redshifts of eight bona fide Hyades white dwarfs, with an accuracy better…
Calibration of the mixing length theory for structures of helium-dominated atmosphere white dwarfs
Cukanovaite E., P. -E. Tremblay, B. Freytag +5
We perform a calibration of the mixing length parameter at the bottom boundary of the convection zone for helium-dominated atmospheres of white dwarfs. This calibration is based on…
Convective Overshoot and Macroscopic Diffusion in Pure-Hydrogen Atmosphere White Dwarfs
Tim Cunningham, Pier-Emmanuel Tremblay, Bernd Freytag +2
We present a theoretical description of macroscopic diffusion caused by convective overshoot in pure-hydrogen DA white dwarfs using three-dimensional (3D), closed-bottom, radiation…
Pure-helium 3D model atmospheres of white dwarfs
E. Cukanovaite, P. -E. Tremblay, B. Freytag +2
We present the first grid of 3D simulations for the pure-helium atmospheres of DB white dwarfs. The simulations were computed with the CO5BOLD radiation-hydrodynamics code and cove…
White Dwarfs In The UKIRT Infrared Deep Sky Survey Data Release 9
P. -E. Tremblay, S. K. Leggett, N. Lodieu +4
We have identified eight to ten new cool white dwarfs from the Large Area Survey (LAS) Data Release 9 of the United Kingdom InfraRed Telescope (UKIRT) Infrared Deep Sky Survey (UKI…
Dynamo action in M-dwarfs
S. B. F. Dorch, B. V. Gudiksen, H. -G. Ludwig
Magnetic activity in M-dwarfs present enigmatic questions: On the one hand they have higher field strengths and larger filling factors than the magnetic field on the Sun, on the ot…
