TOI-2076 and TOI-1807: Two young, comoving planetary systems within 50 pc identified by TESS that are ideal candidates for further follow-up
Christina Hedges, Alex Hughes, Steven Giacalone +42
We report the discovery of two planetary systems around comoving stars; TOI-2076 (TIC 27491137) and TOI-1807 (TIC 180695581). TOI-2076 is a nearby (41.9 pc) multi-planetary system…
Mapping stellar surfaces III: An Efficient, Scalable, and Open-Source Doppler Imaging Model
Rodrigo Luger, Megan Bedell, Daniel Foreman-Mackey +3
The study of stellar surfaces can reveal information about the chemical composition, interior structure, and magnetic properties of stars. It is also critical to the detection and…
Chemical evidence for planetary ingestion in a quarter of Sun-like stars
Lorenzo Spina, Parth Sharma, Jorge Meléndez +5
Stellar members of binary systems are formed from the same material, therefore they should be chemically identical. However, recent high-precision studies have unveiled chemical di…
HD 183579b: A Warm Sub-Neptune Transiting a Solar Twin Detected by TESS
Tianjun Gan, Megan Bedell, Sharon Xuesong Wang +48
We report the discovery and characterization of a transiting warm sub-Neptune planet around the nearby bright ( mag, mag) solar twin HD 183579, delivered by the Tr…
Higher Compact Multiple Occurrence Around Metal-Poor M-Dwarfs and Late K-Dwarfs
Sophie G. Anderson, Jason A. Dittmann, Sarah Ballard +1
The planet-metallicity correlation serves as a potential link between exoplanet systems as we observe them today and the effects of bulk composition on the planet formation process…
