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 Longest-period Young Transiting Exoplanets. A Duo of Puffy Giants inside a Debris Disk

Carlos del Burgo, Alejandro Suárez Mascareño, Ana Heras Pastor +35

We identify two large-radius planets around the F-type star HD 114082 as the longest-period young transiting exoplanets known. From the first transit, detected by NASA's Transiting…

Spin-Orbit Geometry of AU Mic b and c from Back-to-Back Transits Observed Contemporaneously with Magellan PFS, LCOGT, and CHEOPS

Zitao Lin, Gyula M. Szabó, Krzysztof Sz. Zieliński +37

Young planets offer a unique window into the early stages of planetary evolution. AU Mic is one of the nearest (9.8 pc) pre-main sequence stars (~20 Myr), hosting two transiting Ne…

A decade of monitoring the HIP 41378's planetary system

S. Grouffal, A. Santerne, X. Dumusque +32

Multi-planetary systems provide key constraints on planet formation and evolution, as their architecture encodes the dynamical history of planets formed within a common protoplanet…

Transit timing and starspot-induced transit depth variations in the 17 Myr old HIP 67522 system

H. Chakraborty, M. Lendl, A. Nigioni +27

HIP 67522 is a one of the youngest multi-planetary systems discovered to date. The 17 Myr-old, Sun-like star is part of the Scorpius-Centarus OB association and is known to host tw…

An Ultra-Short Period Super-Earth and a Sub-Neptune Orbiting the K dwarf TOI-4311

Yoshi Nike Emilia Eschen, Thomas G. Wilson, Andrew Collier Cameron +95

We report the discovery and characterisation of the multi-planetary system around TOI-4311, a K dwarf kinematically between the Galactic thick disk and Hercules stream. TOI-4311 ho…

RV and TTV Measurements of Two Transiting Long-Period Giants around TOI-4600

Tong Hu, Zitao Lin, Sharon X. Wang +27

TOI-4600b and c, originally identified by the Transiting Exoplanet Survey Satellite (TESS) and reported by I. Mireles et al. (2023), are a rare pair of transiting long-period giant…

Uncovering the Rapidly Evolving Orbits of the Dynamic TOI-201 System

Ismael Mireles, Solène Ulmer-Moll, Donald Liveoak +47

Studying planetary interactions in exoplanet systems informs theories of planet formation and evolution, providing essential context for understanding our own solar system. We comb…

TOI-4616 b: a benchmark Earth-sized planet transiting a nearby M4 dwarf

F. Zong Lang, B. O. Demory, Y. Gomez Maqueo Chew +44

Rocky exoplanets are particularly abundant around M-type stars. Their small radii and low luminosities provide favourable conditions for detecting transiting terrestrial planets an…

An Adolescent and Near-Resonant Planetary System Near the End of Photoevaporation

Mu-Tian Wang, Fei Dai, Hui-Gen Liu +28

Young exoplanets provide vital insights into the early dynamical and atmospheric evolution of planetary systems. Many multi-planet systems younger than 100 Myr exhibit mean-motion…

Two warm sub-Saturn mass planets identified from the TESS Full Frame Images

Felipe I. Rojas, Rafael Brahm, Andrés Jordán +47

Context. Characterization of warm giants is crucial to constrain giant planet formation and evolution. Measuring the mass and radius of these planets, combined with their moderated…

Gas-depleted planet formation occurred in the four-planet system around the red dwarf LHS 1903

Thomas G. Wilson, Anna M. Simpson, Andrew Collier Cameron +173

Small exoplanet radii show two populations, referred to as super-Earths and sub-Neptunes, separated by a gap known as the radius valley. This may be produced by the removal of atmo…

An Ultra-Short Period Super-Earth and Sub-Neptune Spanning the Radius Valley Orbiting the Kinematic Thick Disk Star TOI-2345

Yoshi Nike Emilia Eschen, Thomas G. Wilson, Andrea Bonfanti +94

A crucial chemical link between stars and their orbiting exoplanets is thought to exist. If universal, this connection could affect the formation and evolution of all planets. Ther…

Validation of TESS Planet Candidates with Multi-Color Transit Photometry and TRICERATOPS+

Jonathan Gomez Barrientos, Michael Greklek-McKeon, Heather A. Knutson +33

We present an upgraded version of TRICERATOPS, a software package designed to calculate false positive probabilities for planet candidates identified by the Transiting Exoplanet Su…

An Eccentric Sub-Neptune Moving Into the Evaporation Desert

Sydney Jenkins, Andrew Vanderburg, Ritika Sethi +31

Though missions such as Kepler, K2, and TESS have discovered 2,000 sub-Neptune and Neptunian planets, there is a dearth of such planets at close-in (P3 days) orbits. T…
