MESA Isochrones and Stellar Tracks (MIST) III. The White Dwarf Cooling Sequence
Evan B. Bauer, Aaron Dotter, Charlie Conroy +3
We present a substantial update to the MESA Isochrones and Stellar Tracks (MIST) library, extending the MIST model grids and isochrones down the white dwarf (WD) cooling sequence w…
A super-Chandrasekhar mass type Ia supernova progenitor at 49 pc set to detonate in 23 Gyr
James Munday, Ruediger Pakmor, Ingrid Pelisoli +9
Double white dwarf binaries are a leading explanation to the origin of type Ia supernovae, but no system exceeding the Chandrasekhar mass limit (1.4 M) has been found that…
Comparison of methods used to derive the Galactic star formation history from white dwarf samples
Emily K. Roberts, Pier-Emmanuel Tremblay, Mairi W. O'Brien +4
We compare three methods of deriving the local Galactic star formation history, using as a benchmark the Gaia-defined 40 pc white dwarf sample, currently the largest volume complet…
A network of cooler white dwarfs as infrared standards for flux calibration
Abbigail K. Elms, Nicola Pietro Gentile Fusillo, Pier-Emmanuel Tremblay +6
The accurate flux calibration of observational data is vital for astrophysics and cosmology because absolute flux uncertainties of stellar standards propagate into scientific resul…
white dwarfs within 40 pc III: spectroscopic observations of new candidates in the southern hemisphere
Mairi W. O'Brien, P. -E. Tremblay, N. P. Gentile Fusillo +31
We present a spectroscopic survey of 248 white dwarf candidates within 40 pc of the Sun; of these 244 are in the southern hemisphere. Observations were performed mostly with the Ve…
A white dwarf accreting planetary material determined from X-ray observations
Tim Cunningham, Peter J. Wheatley, Pier-Emmanuel Tremblay +4
The atmospheres of a large proportion of white dwarf stars are polluted by heavy elements that are expected to sink out of visible layers on short timescales. This has been interpr…
