Discovery and Characterization of an Eccentric, Warm Saturn Transiting the Solar Analog TOI-4994
Romy Rodriguez Martinez, Jason D. Eastman, Karen Collins +46
We present the detection and characterization of TOI-4994b (TIC 277128619b), a warm Saturn-sized planet discovered by the NASA Transiting Exoplanet Survey Satellite (TESS). TOI-499…
A giant planet transiting a 3-Myr protostar with a misaligned disk
Madyson G. Barber, Andrew W. Mann, Andrew Vanderburg +35
Astronomers have found more than a dozen planets transiting 10-40 million year old stars, but even younger transiting planets have remained elusive. A possible reason for the lack…
First Calculations of Starspot Spectra based on 3D Radiative Magnetohydrodynamics Simulations
H. N. Smitha, Alexander I. Shapiro, Veronika Witzke +6
Accurate calculations of starspot spectra are essential for multiple applications in astronomy. The current standard is to represent starspot spectra by spectra of stars that are c…
Reliable Transmission Spectrum Extraction with a Three-Parameter Limb Darkening Law
Rosa E. Keers, Alexander I. Shapiro, Nadiia M. Kostogryz +7
Stellar limb darkening must be properly accounted for to accurately determine the radii of exoplanets at various wavelengths. The standard approach to address limb darkening involv…
Most High-density Exoplanets Are Unlikely to Be Remnant Giant-planet Cores
Zifan Lin, Saverio Cambioni, Sara Seager
Some exoplanets have much higher densities than expected from stellar abundances of planet-forming elements. There are two theories - metal-rich formation hypothesis and naked core…
JWST-TST DREAMS: Non-Uniform Dayside Emission for WASP-17b from MIRI/LRS
Daniel Valentine, Hannah R. Wakeford, Ryan C. Challener +23
We present the first spectroscopic characterisation of the dayside atmosphere of WASP-17b in the mid-infrared using a single JWST MIRI/LRS eclipse observation. From forward-model f…
