Spectroscopic data of TESS objects with LAMOST
Stellar parameters and magnetic activity are important for the understanding of stellar physics and dynamo theory. We have used LAMOST spectroscopic surveys to study stellar... -
Exoplanet host stars from LAMOST, TESS, Kepler & K2
Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) low- and medium-resolution spectroscopic surveys are important for determination of the orbital parameters and... -
The Fermi-LAT long-term transient sources (1FLT)
We present the first Fermi Large Area Telescope (LAT) catalog of long-term {gamma}-ray transient sources (1FLT). This comprises sources that were detected on monthly time... -
Solar flare variability from GOES-15 Ly{alpha} obs.
The Lyman-alpha (Ly{alpha}) line of neutral hydrogen at 121.6nm is by far the brightest emission line in the vacuum ultraviolet spectral range of the Sun. The emission at this... -
M-type star magnetic activities from LAMOST & Kepler
We performed a statistical study of magnetic activities of M-type stars by combining the spectra of LAMOST DR5 with light curves from the Kepler and K2 missions. We mainly want... -
Flare catalog through LC data of Kepler DR25
We present a flare catalog of the Kepler mission using the long-cadence data of Data Release 25. This catalog comprises 3420 flare stars and 162262 flare events. A comparison... -
White-light flares on close binaries from Kepler
Based on Kepler data, we present the results of a search for white light flares on 1049 close binaries. We identify 234 flare binaries, of which 6818 flares are detected. We... -
Superflare candidates in ~72000 G-stars
In this work, six convolutional neural networks (CNNs) have been trained based on 15638 superflare candidates on solar-type stars, which are collected from the three years of... -
TESS monitoring campaign of low-mass flare stars
A 20s cadence Transiting Exoplanet Survey Satellite monitoring campaign of 226 low-mass flare stars during Cycle 3 recorded 3792 stellar flares of >=10^32^erg. We explore the... -
X-ray superflares from PMS stars in MYStIX & SFiNCs
Solar-type stars exhibit their highest levels of magnetic activity during their early convective pre-main-sequence (PMS) phase of evolution. The most powerful PMS flares,... -
Kepler and XMM LCs of 3 KIC stars with flares
Solar and stellar flares are powerful events that produce intense radiation across the electromagnetic spectrum. Multiwavelength observations are highly important for... -
X-ray flare LCs of the RS CVn-type star GT Mus
We report that the RS CVn-type star GT Mus (HR 4492, HD101379+HD101380) was the most active star in the X-ray sky in the last decade in terms of the scale of recurrent energetic... -
R-band LC and spectrum of a superstellar flare
We report the detection and follow-up of a superstellar flare GWAC181229A with an amplitude of {Delta}R~9.5mag on an M9-type star by SVOM/GWAC and the dedicated follow-up... -
NGC6334I-MM1 system watermasers spatiokinematics
Following an eruptive accretion event in NGC6334I-MM1, flares in the various maser species, including water masers, were triggered. We report the observed relative proper motion... -
2344 superflares on 266 solar-type stars
We report the latest statistical analyses of superflares on solar-type (G-type main-sequence; effective temperature is 5100-6000K) stars using all of the Kepler primary mission... -
Spectroscopic activity indicators of TIC stars
We present a study of flare rates, rotation periods, and spectroscopic activity indicators of 125 single stars within 15 parsecs and with masses between 0.1 and 0.3M_{sun}... -
Solar coronal mass ejections with SOHO/LASCO
We report on the properties of halo coronal mass ejections (HCMEs) in solar cycles 23 and 24. We compare the HCME properties between the corresponding phases (rise, maximum, and... -
EvryFlare. III. Superflares from Evryscope & TESS
Superflares may provide the dominant source of biologically relevant UV radiation to rocky habitable-zone M-dwarf planets (M-Earths), altering planetary atmospheres and... -
Disturbance storm time index; 1903 Sun outburst
While the Sun is generally more eruptive during its maximum and declining phases, observational evidence shows certain cases of powerful solar eruptions during the quiet phase... -
Global energetics of solar flares. IX.
A more accurate analytical solution of the vertical-current approximation nonlinear force-free field (VCA3-NLFFF) model is presented that includes, besides the radial (Br) and...
