WALTzER: Wide-band Atmospheric Laboratory for Transiting Exoplanet Research

A. G. Sreejith, L. Fossati, M. Lendl +81

Understanding the origin and evolution of planetary atmospheres, and the connection between their lower and upper atmospheric layers, remains a fundamental challenge in exoplanet s…

Searching for hot water world candidates with CHEOPS: II. A low-density super-Earth orbiting the K dwarf TOI-2211

J. A. Egger, P. Cortés-Zuleta, D. Kubyshkina +98

Small exoplanets on close-in orbits are exposed to high levels of stellar irradiation, which can effectively remove low-mass primordial H/He envelopes through atmospheric escape. U…

CHEOPS photometry from 2024 reveals a reversal in the transit-timing variations of AU Mic c

Z. Garai, Gy. M. Szabó, D. Gandolfi +90

We present new CHEOPS transit observations of AU Mic b and AU Mic c obtained between June and September 2024, extending the baseline of transit-timing measurements of this young pl…

The multi-planet system TOI-5624: Four transiting sub-Neptunes with an outer companion revealed by transit-timing variations

A. Bonfanti, D. Gandolfi, P. Leonardi +96

Following the 2022 alert of a TESS object of interest transiting TOI-5624 (a G7 V star 100 pc away), a CHEOPS campaign in 2023 detected four planetary signals at $P_b\approx3…

The supernova Ia progenitor problem in the 2040s

Thomas Kupfer, Simone Scaringi, Ingrid Pelisoli +8

Type Ia supernovae (SNe Ia) are fundamental to cosmology and galactic chemical evolution, yet the nature of their progenitor systems remains unresolved. Multiple evolutionary pathw…

Asteroseismology of white dwarfs in the 2040s

Murat Uzundag, Ingrid Pelisoli, Stephane Charpinet +6

White dwarfs, the final evolutionary stage of the vast majority of stars, serve as critical tools for cosmochronology, studies of planetary system evolution, and laboratories for n…
