Do Faculae Affect Autocorrelation Rotation Periods in Sun-like Stars?
Canis Li, Gibor Basri
Rotational periods derived from autocorrelation (ACF) techniques on stars photometrically similar to the Sun in Kepler data have proven difficult to reliably determine. We investig…
New rotation period measurements of 67,163 Kepler stars
Timo Reinhold, Alexander I. Shapiro, Sami K. Solanki +1
The Kepler space telescope leaves a legacy of tens of thousands of stellar rotation period measurements. While many of these stars show strong periodicity, there exists an even big…
Double-dipping to refine stellar rotation periods
Joanne Tan, Gibor Basri
We present a refined analysis of 15038 Kepler main sequence light curves to determine the stellar rotation periods. The initial period estimates come from an autocorrelation functi…
Measuring periods in aperiodic light curves -- Applying the GPS method to infer rotation periods of solar-like stars
Timo Reinhold, Alexander I. Shapiro, Sami K. Solanki +1
Light curves of solar-like stars are known to show highly irregular variability. As a consequence, standard frequency analysis methods often fail to detect the correct rotation per…
A New Method for Estimating Starspot Lifetimes Based on Autocorrelation Functions
Gibor Basri, Tristan Streichenberger, Connor McWard +4
We present a method that utilizes autocorrelation functions from long-term precision broadband differential light curves to estimate the average lifetimes of starspot groups for tw…
The Information Content in Analytic Spot Models of Broadband Precision Light Curves. II. Spot Distributions and Lifetimes, Global and Differential Rotation
Gibor Basri, Riya Shah
With the advent of space-based precision photometry missions the quantity and quality of starspot light curves has greatly increased. This paper presents a large number of starspot…
