Probing Exoplanetary Chemistry with Ariel: Scientific Priorities and Observational Strategies
Olivia Venot, Yamila Miguel, Robin Baeyens +30
Over the past two decades, increasingly precise observations have revealed that exoplanet atmospheres are chemically diverse and often far from equilibrium, with processes such as…
Radial velocity detection of the TRAPPIST-1 planetary system with SPIRou and NIRPS
Alexandrine L'Heureux, René Doyon, Charles Cadieux +57
The TRAPPIST-1 system is well-known for its seven transiting Earth-sized exoplanets. It has been extensively studied and characterized, notably with transit timing variations (TTVs…
The Leiden/ESA Astrophysics Program for Summer Students (LEAPS)
S. Bellotti, A. D. Sellek, P. Sharda +3
International student mobility plays a critical role in shaping future research careers, particularly in highly globalized fields such as astrophysics. The Leiden/ESA Astrophysics…
Starspots as the origin of ultrafast drifting radio bursts from an active M dwarf
Jiale Zhang, Hui Tian, Stefano Bellotti +16
Detecting coherent radio bursts from nearby M dwarfs provides opportunities for exploring their magnetic activity and interaction with orbiting exoplanets. However, it remains unce…
Solar and Stellar Activity
S. Bellotti, J. Morin
This chapter provides an overview of the magnetic activity of the Sun and stars, discussing its underlying physical origin, manifestations, and fundamental role in exoplanet studie…
First Observation of the Complete Rotation Period of the Ultra-Slowly Rotating Magnetic O Star HD 54879
C. Erba, C. P. Folsom, A. David-Uraz +6
HD 54879 is the most recently discovered magnetic O-type star. Previous studies ruled out a rotation period shorter than 7 years, implying that HD 54879 is the second most slowly-r…
Simulating starspot activity jitter for spectral types F--M: realistic estimates for a representative sample of known exoplanet hosts
S. Bellotti, H. Korhonen
Dark spots on the surface of active stars produce changes in the shapes of the spectral lines that mimic spurious Doppler shifts, compromising the detection of small planets by mea…
Detecting Exoplanets Using Eclipsing Binaries as Natural Starshades
Stefano Bellotti, Ann Zabludoff, Ruslan Belikov +2
We investigate directly imaging exoplanets around eclipsing binaries, using the eclipse as a natural tool for dimming the binary and thus increasing the planet to star brightness c…
