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…
Beyond OCCAM: Measuring Optical Neutron Capture Abundances of Open Cluster Stars
Natalie Myers, Sarah Loebman, Henrique Reggiani +1
Open clusters have long been used to determine ages of stars, as well as calibrate stellar evolution models and other methods of age-dating stellar groups, e.g., gyrochronology, as…
A Spectroscopic Search for Dormant Black Holes in Low-Metallicity Binaries
Pranav Nagarajan, Kareem El-Badry, Henrique Reggiani +9
The discovery of the massive black hole (BH) system Gaia BH3 in pre-release Gaia DR4 data suggests that wide BH binaries with luminous companions may be significantly overrepresent…
Extreme Lithium Depletion in Solar Twins: Challenging Non-Standard Mixing Models
Isabelle Winnick, Jhon Yana Galarza, Henrique Reggiani +12
Lithium (Li) is a powerful tracer of stellar mixing, gradually depleted in solar twins by non-standard transport below the convective zone. Here, we identify six new solar twins wi…
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…
