We include a variety of plots summarizing our training and analysis of HD 173701. Top Left: Kepler and TESS training data, as well as our best fit GP model overlaid. Top Right: RV time series and training posteriors. Bottom: Results of our injection-recovery analysis in the two cases described in §4. The left plots show the preference for models including the injected planet when no GP training is applied. The middle two plots show the improvements gained when training on Kepler or TESS. The rightmost plots highlight the differences between Kepler and TESS training. --astro-ph.EP

Leveraging Precise Photometry From Kepler and TESS to Extract Exoplanets from Radial Velocity Time Series

by Keith CowingDecember 18, 2024December 18, 2024

Stellar activity contamination of radial velocity (RV) data is one of the top challenges plaguing the field of extreme precision RV (EPRV) science. Previous work has shown that photometry can […]

Comparison of bolometric energies and durations of NUV (blue crosses) and optical (red dots) M dwarf flares from this work with those of solar and stellar flares observed with SDO/HMI (black solid stars; Namekata et al. 2017), GALEX (black astericks; Brasseur et al. 2019), DEC (solid diamonds; Webb et al. 2021) and Kepler (open triangles and open squares; Shibayama et al. 2013; Maehara et al. 2015). The cadence sizes are 45 s, 10 s, 20 s, and 1 or 30 min, respectively. The dashed and dotted lines correspond to scaling laws between flare durations and energies corresponding to either constant magnetic field (B) with varying emitting region length scale (L) or constant emitting region length scale with varying magnetic field. -- astro-ph.SR

A Multiwavelength Survey of Nearby M dwarfs: Optical and Near-Ultraviolet Flares and Activity with Contemporaneous TESS, Kepler/K2, Swift, and HST Observations

by Keith CowingApril 19, 2024April 19, 2024

We present a comprehensive multiwavelength investigation into flares and activity in nearby M~dwarf stars. We leverage the most extensive contemporaneous dataset obtained through the Transiting Exoplanet Sky Survey (TESS), Kepler/K2, […]
