The Initial Magnetic Field Distribution in AB Stars
Eoin Farrell, Adam S. Jermyn, Matteo Cantiello +1
Stars are born with magnetic fields, but the distribution of their initial field strengths remains uncertain. We combine observations with theoretical models of magnetic field evol…
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…
starry_process: Interpretable Gaussian processes for stellar light curves
Rodrigo Luger, Daniel Foreman-Mackey, Christina Hedges
In this note we present the starry_process code, which implements an interpretable Gaussian process (GP) for modeling variability in stellar light curves. As dark starspots rotate…
Mapping stellar surfaces II: An interpretable Gaussian process model for light curves
Rodrigo Luger, Daniel Foreman-Mackey, Christina Hedges
The use of Gaussian processes (GPs) as models for astronomical time series datasets has recently become almost ubiquitous, given their ease of use and flexibility. GPs excel in par…
Mapping stellar surfaces I: Degeneracies in the rotational light curve problem
Rodrigo Luger, Daniel Foreman-Mackey, Christina Hedges +1
Thanks to missions like Kepler and TESS, we now have access to tens of thousands of high precision, fast cadence, and long baseline stellar photometric observations. In principle,…
Stellar Rotation in the K2 Sample: Evidence for Modified Spindown
Tyler A. Gordon, James R. A. Davenport, Ruth Angus +5
We analyze light curves of 284,834 unique K2 targets using a Gaussian process model with a quasi-periodic kernel function. By crossmatching K2 stars to observations from Gaia Data…
