Predicting Macroturbulence in F/G/K Dwarfs to 100 m/s Precision
Jack Lubin, Erik Petigura, Kento Masuda +6
We leverage the high resolution and spectral stability of the Keck Planet Finder (KPF) spectrograph to investigate macroturbulence broadening via the stellar cross-correlation func…
Rescuing Kepler's False Positives: A Possible Habitable Zone Exoplanet in the Triple Star System KOI-1623
Rita Lanxuan Wang, Daniel Huber, Daniel Hey +6
The Kepler mission has significantly advanced our understanding of exoplanet demographics. However, Kepler planet candidates showing centroid shifts are often classified as false-p…
Spin-Orbit Alignment of Two Neptune-size Planets Younger than 500 Myr: TOI-560 b and TOI-5082 b
Elina Y. Zhang, Fei Dai, Andrew W. Howard +25
Stellar obliquity measurements provide a direct probe of planetary system dynamics, but remain sparse for Neptune-size planets, particularly at young ages. We present Rossiter-McLa…
Thermal Eclipse Observation of the Young Hot Neptune AU Mic b with Spitzer
Kevin I. Collins, Peter Plavchan, Zachory Berta-Thompson +11
We present the observation of a secondary eclipse of the young hot Neptune, AU Mic b, in the infrared using the Spitzer Space Telescope. Using a primary transit from Spitzer to con…
Kinematic Signatures in the Stellar Halo from Cosmological Encounters between the Milky Way and its Clouds
Mia Mansfield, Robyn Sanderson, Daniel Hey +4
Recent theoretical and observational analysis of the interaction between the Milky Way (MW) and LMC suggest that it has a significant dynamical impact on the MW's stellar halo. We…
RVTESS I: Modeling Asteroseismic Signals with Simultaneous Photometry and RVs
Jiaxin Tang, Sharon X. Wang, Yaguang Li +22
Detecting small planets via the radial velocity method remains challenged by signals induced by stellar variability, versus the effects of the planet(s). Here, we explore using Gau…
