The EBLM Project XI. Mass, radius and effective temperature measurements for 23 M-dwarf companions to solar-type stars observed with CHEOPS

M. I. Swayne, P. F. L. Maxted, A. H. M. J. Triaud +104

Observations of low-mass stars have frequently shown a disagreement between observed stellar radii and radii predicted by theoretical stellar structure models. This ``radius inflat…

Environmental transition: overview of actions to reduce the environmental footprint of astronomy

Lucie Leboulleux, Faustine Cantalloube, Marie-Alice Foujols +15

To keep current global warming below 1.5°C compared with the pre-industrial era, measures must be taken as quickly as possible in all spheres of society. Astronomy must also make i…

The SOPHIE search for northern extrasolar planets-XIX. A system including a cold sub-Neptune potentially transiting a V = 6.5 star HD88986

N. Heidari, I. Boisse, N. C. Hara +51

Transiting planets with orbital periods longer than 40 d are extremely rare among the 5000+ planets discovered so far. The lack of discoveries of this population poses a challenge…

New methods for radial-velocity measurements of double-lined binaries, and detection of a circumbinary planet orbiting TIC 172900988

Lalitha Sairam, Amaury H. M. J. Triaud, Thomas A. Baycroft +8

Ongoing ground-based radial-velocity observations seeking to detect circumbinary planets focus on single-lined binaries even though over nine in every ten binary systems in the sol…

Oblique rings from migrating exomoons: A possible origin for long-period exoplanets with enlarged radii

Melaine Saillenfest, Sophia Sulis, Paul Charpentier +1

Context. The extremely low density of several long-period exoplanets in mature systems is still unexplained -- with HIP 41378 f being archetypical of this category. It has been pro…

Stability and detectability of exomoons orbiting HIP 41378 f, a temperate Jovian planet with an anomalously low apparent density

Caleb K. Harada, Courtney D. Dressing, Munazza K. Alam +21

Moons orbiting exoplanets ("exomoons") may hold clues about planet formation, migration, and habitability. In this work, we investigate the plausibility of exomoons orbiting the te…
