Giant Planets and Eccentric Orbits Are Common Around Galactic Thick Disc Stars
Thiago Ferreira, Jhon Yana Galarza, Henrique Reggiani +15
Planet formation in the Galactic thick disc is expected to be inefficient---low solid reservoirs, short disc lifetimes, and harsh irradiation environments should conspire to inhibi…
Evidence of 1:1 slope between rocky Super-Earths and their host stars
Mykhaylo Plotnykov, Diana Valencia, Alejandra Ross +2
The relationship between the composition of rocky exoplanets and their host stars is fundamental to understanding planetary formation and evolution. However, previous studies have…
Terrestrial Exoplanet Internal Structure Constraints Enabled by Comprehensive Host Star Characterization Reveal that Terrestrial Planets in Mean-motion Resonances are Water Rich
Alejandra Ross, Henrique Reggiani, Kevin C. Schlaufman +2
Exoplanet mass and radius inferences fundamentally rely on host star mass and radius inferences. Despite the importance of host star mass, radius, and elemental abundance inference…
ASASSN-24fw: Candidate circumplanetary disk occultation of a main-sequence star
Nadia L. Zakamska, Gautham Adamane Pallathadka, Dmitry Bizyaev +24
Dusty disks around planetary and substellar companions in outer reaches of exo-planetary systems can be detected as long-lasting occultations, provided the observer is close to the…
SiO and a super-stellar C/O ratio in the atmosphere of the giant exoplanet WASP-121b
Thomas M. Evans-Soma, David K. Sing, Joanna K. Barstow +15
Refractory elements such as iron, magnesium, and silicon can be detected in the atmospheres of ultrahot giant planets. This provides an opportunity to quantify the amount of refrac…
Cloudy mornings and clear evenings on a gas giant exoplanet
Sagnick Mukherjee, David K. Sing, Guangwei Fu +25
The spectra of exoplanet atmospheres are affected by aerosols (clouds and hazes) of uncertain origin. Proposed aerosol formation mechanisms include gas condensation or photochemica…
The discovery and characterization of Earth-crossing asteroid 2024 YR
Bryce T. Bolin, Josef Hanuš, Larry Denneau +9
We describe observations and physical characteristics of Earth-crossing asteroid 2024 YR, discovered on 2024 December 27 by the Asteroid Terrestrial-impact Last Alert System. T…
Refractory and Volatile Species in the UV-to-IR Transmission Spectrum of Ultra-hot Jupiter WASP-178b with HST and JWST
Joshua D. Lothringer, Katherine A. Bennett, David K. Sing +17
The atmospheres of ultra-hot Jupiters are unique compared to other planets because of the presence of both refractory and volatile gaseous species, enabling a new lens to constrain…
TOI-1173 A : The First Inflated Super-Neptune in a Wide Binary System
Jhon Yana Galarza, Thiago Ferreira, Diego Lorenzo-Oliveira +8
Among Neptunian mass exoplanets ( M), puffy hot Neptunes are extremely rare, and their unique combination of low mass and extended radii implies very low density ($…
A Mini-Neptune Orbiting the Metal-poor K Dwarf BD+29 2654
Fei Dai, Kevin C. Schlaufman, Henrique Reggiani +48
We report the discovery and Doppler mass measurement of a 7.4-day 2.3- mini-Neptune around a metal-poor K dwarf BD+29 2654 (TOI-2018). Based on a high-resolution Keck/HIR…
ACCESS: Tentative detection of HO in the ground-based optical transmission spectrum of the low-density hot Saturn HATS-5b
Natalie H. Allen, Néstor Espinoza, Andrés Jordán +13
We present a precise ground-based optical transmission spectrum of the hot-Saturn HATS-5b ( K), obtained as part of the ACCESS survey with the IMACS multi-object spec…
Evidence that the Hot Jupiter WASP-77 A b Formed Beyond Its Parent Protoplanetary Disk's H2O Ice Line
Henrique Reggiani, Kevin C. Schlaufman, Brian F. Healy +2
Idealized protoplanetary disk and giant planet formation models have been interpreted to suggest that a giant planet's atmospheric abundances can be used to infer its formation loc…
