The Kepler mission discovered 2842 exoplanet candidates with 2yr of data. We provide updates to the Kepler planet candidate sample based upon 3yr (Q1-Q12) of data. Through a...

We present revised properties for 196468 stars observed by the NASA Kepler mission and used in the analysis of Quarter 1-16 (Q1-16; May 2009 to Dec 2012) data to detect and...

We report on the masses, sizes, and orbits of the planets orbiting 22 Kepler stars. There are 49 planet candidates around these stars, including 42 detected through transits and...

We provide updates to the Kepler planet candidate sample based upon nearly two years of high-precision photometry (i.e., Q1-Q8). From an initial list of nearly 13400 threshold...

New transiting planet candidates are identified in 16 months (2009 May-2010 September) of data from the Kepler spacecraft. Nearly 5000 periodic transit-like signals are vetted...

We derive detailed theoretical models for 1074 nearby stars from the SPOCS (Spectroscopic Properties of Cool Stars) Catalog. We provide a catalog of physical parameters for 1074...

The ages of solar-like stars have been at the center of many studies such as exoplanet characterization or Galactic-archeology. While ages are usually computed from stellar...

We investigate the angular momentum of mono-abundance populations (MAPs) of the Milky Way thick disk by using a sample of 26,076 giant stars taken from APOGEE Data Release (DR)...

HI Ly{alpha} (1215.67{AA}) and the OI triplet (1302.17, 1304.86, and 1306.03{AA}) are bright far-ultraviolet (FUV) emission lines that trace the stellar chromosphere....

The physical properties of transiting exoplanets are connected with the physical properties of their host stars. We present a homogeneous spectroscopic analysis based on the...

During the Zwicky Transient Facility (ZTF) Phase I operations, 78 hydrogen-poor superluminous supernovae (SLSNe-I) were discovered in less than 3yr, constituting the largest...

In order to better characterize the rich supernova remnant (SNR) population of M83 (NGC 5236), we have obtained high-resolution (~85km/s) spectra of 119 of the SNRs and SNR...

We present the first results from our ongoing project to study extremely low-mass (ELM) white dwarfs (WDs) (M<~0.3M{sun}) with the Large Sky Area Multi-Object Fiber...

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...

Stellar rotation is a complex function of mass, metallicity, and age and can be altered by binarity. To understand the importance of these parameters in main-sequence stars, we...

We present Markov Chain Monte Carlo radiative transfer modeling of a joint ALMA 345GHz and spectral energy distribution data set for a sample of 97 protostellar disks from the...

Solar and stellar flares are powerful events that produce intense radiation across the electromagnetic spectrum. Multiwavelength observations are highly important for...

The projected stellar rotational velocity (vsini) is critical for our understanding of processes related to the evolution of angular momentum in pre-main-sequence stars. We...

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...

We present an investigation of the magnetic activity and flare characteristics of the subgiant stars mostly from F and G spectral types and compare the results with the...
