Helium escaping from the atmosphere of a nearby rocky exoplanet orbiting in a habitable zone

Collin Cherubim, Shreyas Vissapragada, Tim Cunningham +13

Observations of highly irradiated gas giant exoplanets have shown helium escaping from their atmospheres. There is limited evidence for atmospheres on rocky exoplanets, perhaps bec…

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…

Hydrogen airglow from an escaping ultrahot Jupiter atmosphere

Yapeng Zhang, Chenliang Huang, Aaron Householder +17

Intense high-energy irradiation of close-in gaseous exoplanets drives the rapid escape of their atmospheres, fundamentally shaping planetary demographics. While atmospheric loss is…

Photochemical Production of CS2 in Temperate-to-Warm Gas Giant Exoplanet Atmospheres

Jeehyun Yang, Vighnesh Nagpal, Michael Zhang +16

Sulfur chemistry has emerged as an important probe of exoplanet atmospheres in the JWST era, although observational constraints have thus far been largely limited to SO2 and H2S in…

Horizontal transport as a source of disequilibrium chemistry on the nightside of a hot exoplanet

Vivien Parmentier, Kevin B. Stevenson, Luis Welbanks +15

Hot Jupiters have temperature gradients of several hundreds of degrees between their permanent day and nightsides. In equilibrium, the primary carbon reservoir is expected to trans…

Characterizing the bolometric-photoevaporative transition in young sub-Neptunes with radiation-hydrodynamic simulations

William Misener, Matthäus Schulik, Hilke E. Schlichting +1

Hydrodynamic atmospheric escape plays a central role in shaping the demographics of small, close-in exoplanets. Two mechanisms have been proposed to drive mass loss: photoevaporati…

The T16 Planet Hunt: 10,000 New Planet Candidates from TESS Cycle 1 and the Confirmation of a Hot Jupiter Around TIC 183374187

Joshua T. Roth, Joel D. Hartman, Gáspár Á. Bakos +12

The T16 project has produced a uniformly detrended and systematics-corrected set of 83,717,159 TESS Cycle 1 full-frame image light curves for stars observed by TESS in its primary…

A scaling relation for core heating by giant impacts and implications for dynamo onset

You Zhou, Peter E. Driscoll, Mingming Zhang +2

Accretional heating of Earth's interior during formation is pivotal to its subsequent thermal and chemical evolution. In particular, impact heating of Earth's core is expected, but…

How leaky? A large parameter study of leaky dust traps to quantify the transport of pebbles and ice in protoplanetary discs

Adrien Houge, Anders Johansen, Andrea Banzatti +1

In protoplanetary discs, the presence of dust traps can significantly alter the transport of solids from the outer to the inner regions, and hence they are often invoked as an expl…

Searching for GEMS: Three warm Saturns and a super-Jupiter orbiting four early M-dwarfs

Pranav H. Premnath, Paul Robertson, Shubham Kanodia +33

We report the confirmation and characterization of four transiting giant planets orbiting early-M dwarfs discovered by the Searching for Giant Exoplanets around M-dwarf Stars (GEMS…

Evidence for an Atmosphere on the Ultra-Short Period super-Earth HD 3167 b

Brandon Park Coy, Qiao Xue, Megan Weiner Mansfield +14

'Lava worlds'-Earth-sized planets hot enough (Teq >~ 1100 K) to melt their dayside silicate surfaces-have emerged as promising candidates for atmospheric detection and characteriza…

The compositions of the HR 8799 planets reflect accretion of both solids and metal-enriched gas

Jerry W. Xuan, Jean-Baptiste Ruffio, Yayaati Chachan +24

With four giant planets (, $T_\rm{eff}\sim900-1200$ K) orbiting between 15-70 au, HR 8799 provides an unparalleled testbed for studying giant planet formatio…

Global Abiotic Sulfur Cycling on Earth-like Terrestrial Planets

Rafael Rianço-Silva, Javed Akhter Mondal, Matthew A. Pasek +3

Sulfur is a redox active element that may have helped mediate an electron flow that kickstarted life and which presently is an essential element for all life on Earth. Despite curr…
