  journal={arXiv: Solar and Stellar Astrophysics},
We measure photometric rotation periods and starspot amplitudes in Evryscope light curves for 113 cool stars selected to have strong flaring. The Evryscope array of small telescopes has observed all bright nearby stars in the Southern sky, producing two minute cadence light curves since 2016. Long-term, high-cadence observations allow detection of rare flare events and long-term periodic variability, and provide tools to probe the complex relationship between stellar rotation, starspots, and… Expand

Superflares and variability in solar-type stars with TESS in the Southern hemisphere
Superflares on solar-type stars have been a rapidly developing field ever since the launch of Kepler. Over the years, there have been several studies investigating the statistics of these explosiveExpand
Evryscope-South Survey of Upper- and Pre-main Sequence Solar Neighborhood Stars
Using photometric data collected by Evryscope-South, we search for nearby young variable systems on the upper main sequence and pre-main sequence. The Evryscopes are all-sky high-cadence telescopeExpand
K2 Ultracool Dwarfs Survey – VI. White light superflares observed on an L5 dwarf and flare rates of L dwarfs
Kepler K2 long cadence data are used to study white light flares in a sample of 45 L dwarfs. We identified 11 flares on 9 L dwarfs with equivalent durations of (1.3 - 198) hr and totalExpand


EvryFlare. I. Long-term Evryscope Monitoring of Flares from the Cool Stars across Half the Southern Sky
We search for superflares from 4,068 cool stars in 2+ years of Evryscope photometry, focusing on those with high-cadence data from both Evryscope and TESS. The Evryscope array of small telescopesExpand
Variables in the Southern Polar Region Evryscope 2016 Data Set
The regions around the celestial poles offer the ability to find and characterize long-term variables from ground-based observatories. We used multi-year Evryscope data to search for high-amplitudeExpand
Complex Rotational Modulation of Rapidly Rotating M Stars Observed with TESS
We have searched for short periodicities in the light curves of stars with $T_{\rm eff}$ cooler than 4000 K made from 2-minute cadence data obtained in TESS sectors 1 and 2. Herein we report theExpand
Stellar Flares from the FirstTESSData Release: Exploring a New Sample of M Dwarfs
We perform a study of stellar flares for the 24,809 stars observed with 2 minute cadence during the first two months of the TESS mission. Flares may erode exoplanets' atmospheres and impact theirExpand
Stellar Properties of Active G and K Stars: Exploring the Connection between Starspots and Chromospheric Activity
We gathered high resolution spectra for an ensemble of 55 bright active and inactive stars using the ARC 3.5 m Telescope Echelle Spectrograph at Apache Point Observatory ($R\approx$31,500). WeExpand
K2 Ultracool Dwarfs Survey – V. High superflare rates on rapidly rotating late-M dwarfs
We observed strong superflares (defined as flares with energy in excess of 1033 erg) on three late-M dwarfs: 2MASS J08315742+2042213 (hereafter 2M0831+2042; M7 V), 2MASS J08371832+2050349Expand
The Revised TESS Input Catalog and Candidate Target List
We describe the catalogs assembled and the algorithms used to populate the revised TESS Input Catalog (TIC), based on the incorporation of the Gaia second data release. We also describe a revisedExpand
Scikit-learn: Machine Learning in Python
Scikit-learn is a Python module integrating a wide range of state-of-the-art machine learning algorithms for medium-scale supervised and unsupervised problems. This package focuses on bringingExpand
