The Merger Fraction of Ultramassive White Dwarfs
Mukremin Kilic, Adam G. Moss, Alekzander Kosakowski +6
We search for merger products among the 25 most massive white dwarfs in the Montreal White Dwarf Database 100 pc sample through follow-up spectroscopy and high-cadence photometry.…
The HST large programme on NGC 6752 -- IV. The White Dwarf Sequence
L. R. Bedin, M. Salaris, J. Anderson +13
We present our final study of the white dwarf cooling sequence (WD CS) in the globular cluster NGC 6752. The investigation is the main goal of a dedicated Hubble Space Telescope la…
Toward a systematic cartography of the chemical stratification inside white dwarfs from deep asteroseismic probing of ZZ Ceti stars
S. Charpinet, N. Giammichele, P. Brassard +5
DA-type white dwarfs account for 80% of all white dwarfs and represent, for most of them, the ultimate outcome of the typical evolution of low-to-intermediate mass stars. Their int…
The HST Large Programme on NGC 6752. I. Serendipitous discovery of a dwarf Galaxy in background
L. R. Bedin, M. Salaris, R. M. Rich +12
As part of a large Hubble Space Telescope investigation aiming at reaching the faintest stars in the Galactic globular cluster NGC 6752, an ACS/WFC field was the subject of deep op…
On the Spectral Evolution of Helium-Atmosphere White Dwarfs Showing Traces of Hydrogen
Benoit Rolland, Pierre Bergeron, Gilles Fontaine
We present a detailed spectroscopic analysis of 115 helium-line (DB) and 28 cool, He-rich hydrogen-line (DA) white dwarfs based on atmosphere fits to optical spectroscopy and photo…
The Canada-France Imaging Survey: First results from the u-band component
Rodrigo Ibata, Alan McConnachie, Jean-Charles Cuillandre +41
The Canada-France Imaging Survey (CFIS) will map the northern high Galactic latitude sky in the -band ("CFIS-u", 10,000) and in the -band ("CFIS-r", 5,000$\,…
