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

Context. Though efforts to detect them have been made with a variety of methods, no
technique can claim a successful, confirmed detection of a moon outside the Solar System …

HIP 41378 d is a long-period planet that has only been observed to transit twice, three years
apart, with K2. According to stability considerations and a partial detection of the Rossiter …

ABSTRACT Cool gaseous exoplanets (1.75 R⊕< R p< 3 RJ, 200 K< T eq< 1000 K) are an
as-yet understudied population, with great potential to expand our understanding of …

Several stars show deep transits consistent with discs of roughly seen at moderate
inclinations, likely surrounding planets on eccentric orbits. We show that this configuration …

After 25 years of the prediction of the possibility of observations, and despite the many
hundreds of well-studied transiting exoplanet systems, we are still waiting for the …

HIP 41378 f is a sub-Neptune exoplanet with an anomalously low density. Its long orbital
period and deep transit make it an ideal candidate for detecting oblateness photometrically …

Increasingly precise space-based photometry uncovers higher-order effects in transits,
eclipses and phase curves which can be used to characterize exoplanets in novel ways. The …

Recent works suggest that, in multiplanetary systems, a close-in exoplanet can sometimes
avoid becoming tidally locked to its host star if it is captured into a secular spin-orbit …

The super-puff HIP-41378 f represents a fascinating puzzle due to its anomalously low
density on a far-out orbit in contrast with other known super-puffs. In this work, we explore …
