Scalable Bayesian Additive Models for Stellar Flare Detection via Amortized Gaussian Process Inference and Hidden Markov Models
Rodrigo Herrera, Vianey Leos-Barajas, Gwendolyn Eadie +2
Gaussian Processes (GPs) are a powerful tool for Bayesian time-series modeling, yet their cubic computational cost remains a severe barrier for application to long, high-cadence da…
The Range of Cumulative XUV Flux on GJ 1132 b
Rory Barnes, Laura N. R. do Amaral, Jessica Birky +4
We investigate the plausible history of the XUV luminosity evolution of the planet-hosting M4 star GJ 1132 (~0.2 solar masses) to infer the cumulative incident XUV flux intercepted…
Automated Spectroscopic Wavelength Calibration using Dynamic Time Warping
James R. A. Davenport, Francisca Chabour Barra, K. Azalee Bostroem +14
Here we present an automated method for obtaining wavelength calibrations for one-dimensional spectra, using Dynamic Time Warping (DTW). DTW is a flexible and well-understood algor…
Prospects of Constraining Equilibrium Tides in Low-Mass Binary Stars
Jessica Birky, Rory K. Barnes, James R. A. Davenport
The dynamical evolution of short-period low-mass binary stars (with mass , from formation to the late main-sequence, and with orbital periods less than 10 d…
Tidal Synchronization of TESS Eclipsing Binaries
Marshall Hobson-Ritz, Jessica Birky, Leah Peterson +7
Tidal synchronization plays a fundamental role in the evolution of binary star systems. However, key details such as the timescale of synchronization, efficiency of tidal dissipati…
