Planetary atmospheric escape and disk formation around WDJ0914+1914
C. Villarreal D'Angelo, M. P. Ronco, M. R. Schreiber +3
The spectrum of the white dwarf WD J091405.30+191412.25 displays the absorption and double-peaked emission lines of the volatiles hydrogen, oxygen, and sulfur. This unique characte…
A formation pathway for giant planets in S-type discs of γ-Cephei-like compact binaries
MarÃa 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 a…
Predicted incidence of Jupiter-like planets around white dwarfs
Alex Mauch-Soriano, Matthias R. Schreiber, Diego Correa +7
Only a handful of gas giant planets orbiting white dwarfs are known. It remains unclear whether this paucity reflects observational challenges or the consequences of stellar evolut…
The PAIRS project: a global formation model for planets in binaries. I. Effect of disc truncation on the growth of S-type planets
Julia Venturini, Arianna Nigioni, Maria Paula Ronco +2
Binary stars are as common as single stars. The number of detected planets orbiting binaries is rapidly increasing thanks to the synergy between transit surveys, Gaia and high-reso…
Detailed spectroscopic and photometric analysis of the remarkable planet-hosting wide binary system HD 202772A/B
Emiliano Jofré, Yilen Gómez Maqueo Chew, Romina Petrucci +15
We conducted a detailed spectroscopic and photometric characterization of the planet-hosting wide binary HD 202772A/B. No planet has been detected around HD 202772B, whereas HD 202…
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 +4
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…
