gr8stars II : judgement day for spectroscopic parameter model systematics
Alix Violet Freckelton, Annelies Mortier, Megan Bedell +18
Many areas of astrophysics, including exoplanetary studies, rely on precise and accurate stellar parameters. This demands that uncertainties on these parameters truly reflect all b…
Metal Pipe: A Broadly-Applicable Stellar Abundance Pipeline Using Isochronal Parameters
Jared R. Kolecki, Lauren M. Weiss
Characterizing exoplanet host stars at a population level requires a method of homogeneously characterizing stellar properties across all spectral types. To this end, we have devel…
The Compositions of Rocky Planets in Close-in Orbits Tend to be Earth-Like
Casey L. Brinkman, Lauren M. Weiss, Daniel Huber +54
Hundreds of exoplanets between 1-1.8 times the size of the Earth have been discovered on close in orbits. However, these planets show such a diversity in densities that some appear…
A Reanalysis of the Composition of K2-106b: an Ultra-short Period Super-Mercury Candidate
Romy Rodríguez Martínez, B. Scott Gaudi, Joseph G. Schulze +9
We present a reanalysis of the K2-106 transiting planetary system, with a focus on the composition of K2-106b, an ultra-short period, super-Mercury candidate. We globally model exi…
A Clear View of a Cloudy Brown Dwarf Companion from High-Resolution Spectroscopy
Jerry W. Xuan, Jason Wang, Jean-Baptiste Ruffio +37
Direct imaging studies have mainly used low-resolution spectroscopy () to study the atmospheres of giant exoplanets and brown dwarf companions, but the presence of clo…
Retrieving the C and O Abundances of HR 7672~AB: a Solar-Type Primary Star with a Benchmark Brown Dwarf
Ji Wang, Jared R. Kolecki, Jean-Baptiste Ruffio +30
A benchmark brown dwarf (BD) is a BD whose properties (e.g., mass and chemical composition) are precisely and independently measured. Benchmark BDs are valuable in testing theoreti…
Measuring Elemental Abundances of JWST Target Stars for Exoplanet Characterization I. FGK Stars
Jared R. Kolecki, Ji Wang
With the launch of the JWST, we will obtain more precise data for exoplanets than ever before. However, this data can only inform and revolutionize our understanding of exoplanets…
Elemental abundances of nearby M dwarfs based on high-resolution near-infrared spectra obtained by the Subaru/IRD survey: Proof of concept
Hiroyuki Tako Ishikawa, Wako Aoki, Teruyuki Hirano +24
Detailed chemical analyses of M dwarfs are scarce but necessary to constrain the formation environment and internal structure of planets being found around them. We present element…
Searching For Transiting Planets Around Halo Stars. I. Sample Selection and Validation
Jared R. Kolecki, Ji Wang, Jennifer A. Johnson +3
By measuring the elemental abundances of a star, we can gain insight into the composition of its initial gas cloud -- the formation site of the star and its planets. Planet formati…
