XGAPS: a sub-arcsecond cross-match of Galactic Plane Surveys
S. Scaringi, M. Monguio, C. Knigge +5
We present a sub-arcsecond cross-match of Gaia Data Release 3 (DR3) against the INT Galactic Plane Surveys (IGAPS) and the United Kingdom Infrared Deep Sky Survey (UKIDSS). The res…
The White Dwarf Binary Pathways Survey -- IX. Three long period white dwarf plus subgiant binaries
S. G. Parsons, M. S. Hernandez, O. Toloza +8
Virtually all binaries consisting of a white dwarf with a non-degenerate companion can be classified as either close post-interaction systems (with orbital periods of a few days or…
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…
The White Dwarf Binary Pathways Survey -- VIII: a post common envelope binary with a massive white dwarf and an active G-type secondary star
M. S. Hernandez, M. R. Schreiber, S. G. Parsons +6
The white dwarf binary pathways survey is dedicated to studying the origin and evolution of binaries containing a white dwarf and an intermediate-mass secondary star of the spectra…
The C/N ratio from FUV spectroscopy as a constraint upon the past evolution of HS0218+3229
O. Toloza, Boris T. Gaensicke, Laura M. Guzman-Rincon +8
Some white dwarfs accreting from non-degenerate companions show anomalous carbon and nitrogen abundances in the photospheres of their stellar components which have been postulated…
Testing Lyman alpha emission line reconstruction routines at multiple velocities in one system
David J. Wilson, Allison Youngblood, Odette Toloza +6
The 1215.67A HI Lyman alpha emission line dominates the ultraviolet flux of low mass stars, including the majority of known exoplanet hosts. Unfortunately, strong attenuation by th…
Modules for Experiments in Stellar Astrophysics (MESA): Time-Dependent Convection, Energy Conservation, Automatic Differentiation, and Infrastructure
Adam S. Jermyn, Evan B. Bauer, Josiah Schwab +19
We update the capabilities of the open-knowledge software instrument Modules for Experiments in Stellar Astrophysics (MESA). The new auto_diff module implements automatic different…
The White Dwarf Binary Pathways Survey VII: Evidence for a bi-modal distribution of post mass transfer systems?
F. Lagos, M. R. Schreiber, S. G. Parsons +5
Binary systems consisting of a white dwarf and a main-sequence companion with orbital periods up to d are often thought to be formed through common envelope evolution…
The White Dwarf Binary Pathways Survey VI: two close post common envelope binaries with TESS light curves
M. S. Hernandez, M. R. Schreiber, S. G. Parsons +9
Establishing a large sample of post common envelope binaries (PCEBs) that consist of a white dwarf plus an intermediate mass companion star of spectral type AFGK, offers the potent…
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…
