Studying hot evolved stars with ultraviolet spectroscopy
Stephan Geier, Nicole Reindl, Matti Dorsch +7
Hot evolved stars are key objects to reconstruct the various evolutionary pathways of Sun-like stars, to probe binary interactions and the physics of supernovae. They serve as powe…
A formation pathway for giant planets in S-type discs of γ-Cephei-like compact binaries
María Paula Ronco, Octavio M. Guilera, Julia Venturini +2
Planet formation in close binary systems such as -Cephei is strongly challenged by the truncation of the circumprimary disc induced by the stellar companion, which limits the av…
Stars on the ascending helium giant branch I. From white dwarf merger to helium giant: the evolutionary state of the rapidly rotating hot subdwarf HE 1518-0948
M. Pritzkuleit, M. Dorsch, M. M. Miller Bertolami +3
Hot subdwarf stars with masses above ascend the helium giant branch after the end of core helium burning, before entering the white dwarf cooling track or exploding a…
Two hot pre-white dwarfs inside the red-giant-branch planetary nebula Pa 13 -- Double core evolution or common envelope-induced rejuvenation?
Nicole Reindl, David Jones, Todd Hillwig +4
Close binary central stars of PNe offer a unique window for investigating the conditions immediately following the ejection of a common envelope (CE). Double eclipsing and double-l…
Observing bright pulsating white dwarfs with PLATO: A new window into the late stages of stellar evolution
Murat Uzundag, Alejandro H. Corsico, Nicholas Jannsen +17
We present the scientific case for exploiting the capabilities of the PLATO mission to study bright pulsating white dwarfs across a wide spectral range, including hydrogen-deficien…
Protoplanetary disc population synthesis I. Linking mass-dependent viscosity, star formation history and environment to observations
Jose L. Gomez, Octavio M. Guilera, Marcelo M. Miller Bertolami +2
Context. Recent studies highlight the importance of stellar mass sampling when determining disc lifetimes through observed disc fractions. Low-mass stars host discs with average li…
