Detection of a weak magnetic field in the Balmer emission line white dwarf WDJ1653-1001
Abbigail Elms, Stefano Bagnulo, Pier-Emmanuel Tremblay +8
The small DAHe and DAe spectral classes comprise isolated, hydrogen-dominated atmosphere white dwarfs that exhibit variable photometric flux and Balmer line emission. These mysteri…
Classifying white dwarfs from multi-object spectroscopy surveys with machine learning
James Munday, Pier-Emmanuel Tremblay, Ingrid Pelisoli +5
With tens to hundreds of spectra of white dwarfs being taken each night from multi-object spectroscopic surveys, automated spectral classification is essential as part of efficient…
The DBL Survey II: towards a mass-period distribution of double white dwarf binaries
James Munday, Ingrid Pelisoli, Pier-Emmanuel Tremblay +14
Double white dwarf binaries are an important remnant of binary evolution as they are possible type Ia supernova progenitors and strong sources of gravitational waves in the low-fre…
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…
