Confirmation of Fe I on MASCARA-5 b's Dayside Observed With EXPRES
James T. Sikora, Joe Llama, Rachael M. Roettenbacher +5
MASCARA-5~b/TOI-1431~b is an ultra-hot Jupiter \citep[, , , $R_{\rm p}=…
The Effects of Sunspots on Spectral Line Shapes in the Visible
Claire Komori, John M. Brewer, Lily L. Zhao
We present a comparative spectral analysis to explore the ability of a cooler Sun model to accurately capture the spectral line shape changes caused by Sunspots. In the search for…
An Earth-like Density for the Temperate Earth-sized Planet GJ 12b
Madison Brady, Jacob Bean, Ritvik Basant +9
While JWST has provided us with the opportunity to probe the atmospheres of potentially-habitable planets, observations of the TRAPPIST-1 system have shown us that active stars sev…
gr8stars I: A homogeneous spectroscopic study of bright FGKM dwarfs and a public library of their high-resolution spectra
Alix Violet Freckelton, Annelies Mortier, Megan Bedell +15
As the fields of stellar and exoplanetary study grow and revolutionary new detection instruments are created, it is imperative that a homogeneous, precise source of stellar paramet…
The influence of chromospheric activity on line formation
Mariela C. Vieytes, Lily L. Zhao, Megan Bedell
One of the primary sources of stellar spectral variability is magnetic activity. While our current understanding of chromospheric activity is largely derived from specific lines se…
Peering into the black box: forward-modeling the uncertainty budget of high-resolution spectroscopy of exoplanet atmospheres
Arjun B. Savel, Megan Bedell, Eliza M. -R. Kempton +6
Ground-based high-resolution cross-correlation spectroscopy (HRCCS; R >~ 15,000) is a powerful complement to space-based studies of exoplanet atmospheres. By resolving individual s…
