Resolving the Young 2 Cygni Run-away Star into a Binary using iLocater

Justin R. Crepp, Jonathan Crass, Andrew J. Bechter +30

Precision radial velocity (RV) spectrographs that use adaptive optics (AO) show promise to advance telescope observing capabilities beyond those of seeing-limited designs. We are b…

Constraints on the Early Luminosity History of the Sun: Applications to the Faint Young Sun Problem

Connor Basinger, Marc Pinsonneault, Sandra T. Bastelberger +2

Stellar evolution theory predicts that the Sun was fainter in the past, which can pose difficulties for understanding Earth's climate history. One proposed solution to this Faint Y…

An Earth-Mass Planet and a Brown Dwarf in Orbit Around a White Dwarf

Keming Zhang, Weicheng Zang, Kareem El-Badry +8

Terrestrial planets born beyond 1-3 AU have been theorized to avoid being engulfed during the red-giant phases of their host stars. Nevertheless, only a few gas-giant planets have…

The PEPSI Exoplanet Transit Survey (PETS). V: New Na D transmission spectra indicate a quieter atmosphere on HD 189733b

E. Keles, S. Czesla, K. Poppenhaeger +23

Absorption lines from exoplanet atmospheres observed in transmission allow us to study atmospheric characteristics such as winds. We present a new high-resolution transit time-seri…

OGLE-2015-BLG-0845L: A low-mass M dwarf from the microlensing parallax and xallarap effects

Zhecheng Hu, Wei Zhu, Andrew Gould +51

We present the analysis of the microlensing event OGLE-2015-BLG-0845, which was affected by both the microlensing parallax and xallarap effects. The former was detected via the sim…

Searching for Free-Floating Planets with TESS: Results from Sectors 61-65

Michelle Kunimoto, William DeRocco, Nolan Smyth +2

Though free-floating planets (FFPs) may outpopulate their bound counterparts in the terrestrial-mass range, they remain one of the least explored exoplanet demographics. Due to the…
