The double degenerate LP400-22 revisited
S. Vennes, A. Kawka, T. R. Vaccaro +1
We re-examine the properties of the high-velocity and extremely low mass white dwarf LP 400-22 and its close companion. Based on an extended observation timeline we determined a bi…

A new extremely low-mass white dwarf in the NLTT catalogue
A. Kawka, S. Vennes
We report on the discovery of the extremely low-mass, hydrogen-rich white dwarf, NLTT 11748. Based on measurements of the effective temperature (8540+/-50 K) and surface gravity (l…

Spectroscopic observations of high proper motion DA white dwarfs
E. Arazimova, A. Kawka, S. Vennes
We used the revised New Luyten Two-Tenths (rNLTT) catalog to select high proper motion white dwarf candidates. We studied the spectra of 70 hydrogen-rich (DA) white dwarfs, which w…
