The ESO supernovae type Ia progenitor survey (SPY)
R. Napiwotzki, C. A. Karl, T. Lisker +13
Close double degenerate binaries are one of the favoured progenitor channels for type Ia supernovae, but it is unclear how many suitable systems there are in the Galaxy. We report…
Axions and the luminosity function of white dwarfs. The thin and thick disks, and the halo
Jordi Isern, Enrique Garcia-Berro, Santiago Torres +2
The evolution of white dwarfs is a simple gravothermal process of cooling. Since the shape of their luminosity function is sensitive to the characteristic cooling time, it is possi…
A search for white dwarfs in the Galactic plane: the field and the open cluster population
R. Raddi, S. Catalan, B. T. Gaensicke +13
We investigated the prospects for systematic searches of white dwarfs at low Galactic latitudes, using the VLT Survey Telescope (VST) H Photometric Survey of the Galactic plane…
Supernova 2014J at M82: II. Direct Analysis of Spectra Obtained with Isaac Newton and William Herschel Telescopes
Patrick Vallely, M. E. Moreno-Raya, E. Baron +19
We analyze a time series of optical spectra of SN~2014J from almost two weeks prior to maximum to nearly four months after maximum. We perform our analysis using the SYNOW code, wh…
The substellar companion in the eclipsing white dwarf binary SDSS J141126.20+200911.1
S. P. Littlefair, S. L. Casewell, S. G. Parsons +14
We present high time resolution SDSS- and SDSS- light curves of the primary eclipse in SDSS J141126.20+200911.1, together with time-resolved X-Shooter spectroscopy and near…
White paper: Gaia and the end states of stellar evolution
M. A Barstow, S. L. Casewell, S. Catalan +18
This is the product of a Gaia GREAT workshop on "Gaia and the end states of stellar evolution" held at the University of Leicester in April 2011.
