Observational Signatures of Planetary Tidal Disruption Events Around Solar-Mass Stars
MatÃas Montesinos, Sergei Nayakshin, Vardan Elbakyan +4
The tidal disruption of planets by their host stars represents a growing area of interest in transient astronomy, offering insights into the final stages of planetary system evolut…
Two warm Earth-sized exoplanets and an Earth-sized candidate in the M5V-M6V binary system TOI-2267
S. Zúñiga-Fernández, F. J. Pozuelos, M. Dévora-Pajares +63
We report two warm Earth-sized exoplanets orbiting the close binary TOI-2267 (M5+M6, separation ~8 au). Data from TESS and ground-based facilities confirm the planets, but we canno…
Volatile enrichment in low-mass planets: Signatures of past planetary disruption?
Mario Sucerquia, MatÃas Montesinos, Ana MarÃa Agudelo +1
Tidal disruption and engulfment events around main-sequence stars -- such as the luminous red nova ZTF SLRN-2020, a candidate planetary-engulfment event -- reveal the destruction o…
Orbital Decay of the Ultra-Hot Jupiter TOI-2109b: Tidal Constraints and Transit-Timing Analysis
Jaime A. Alvarado-Montes, Mario Sucerquia, Jorge I. Zuluaga +1
TOI-2109b is the ultra-hot Jupiter with the shortest orbital period (hr) yet discovered. At this close distance, strong tidal interactions can produce a significant excha…
Ionized envelopes around protoplanets and the role of radiative feedback in gas accretion
MatÃas Montesinos, Juan Garrido-Deutelmoser, Jorge Cuadra +5
Planetary growth within protoplanetary disks involves accreting material from their surroundings, yet the underlying mechanisms and physical conditions of the accreting gas remain…
Extreme exomoons in WASP-49 Ab: dynamics and detectability
Mario Sucerquia, Nicolás Cuello.
WASP-49Ab, a low-density, Saturn-like planet in a tight orbit around a Sun-like star within a wide binary system, is a compelling candidate for hosting a volcanic moon, as suggeste…
