We use PyDynamicaLC, a model using the least number of--and the least correlated--degrees of freedom needed to derive a photodynamical model, to describe some of the...

Planetary radii are derived for 218 exoplanets orbiting 161 M dwarf stars. Stellar radii are based on an analysis of APOGEE high-resolution near-IR spectra for a subsample of...

The Orion Nebula Cluster (ONC) provides the closest example of ongoing star and planet formation in highly irradiated environments. In particular, it is a key region to study...

We have compiled a list of blue lurker (BL) candidates in open clusters using the available rotation catalogs. Blue lurkers are rejuvenated main-sequence stars hidden among...

Recent observations with the LOw Frequency ARray (LOFAR) have revealed 19 nearby M dwarfs showing bright circularly polarised radio emission. One of the possible sources of such...

We present new angular diameter measurements for 33 stars from the Navy Precision Optical Interferometer, reaching uncertainties on the limb-darkened diameter of 2% or less for...

In the era of astronomical big data, more than one million contact binaries have been discovered. Traditional approaches of light-curve analysis are inadequate for investigating...

This bibliographic catalogue lists radii of line emitting regions around more than 100 Be stars determined from high signal to noise registrations of emission line profiles,...

Detached eclipsing binary star systems are our primary source of measured physical properties of normal stars. I introduce DEBCat: a catalog of detached eclipsing binaries with...

The Gaia Data Release 1 (DR1) sample of white dwarf parallaxes is presented, including six directly observed degenerates and 46 white dwarfs in wide binaries. This data set is...

We classified the reddest (r-J>2.2) stars observed by the NASA Kepler mission into main-sequence dwarf or evolved giant stars and determined the properties of 4216 M dwarfs...

Thanks to the recent very high precision photometry of red giants from satellites such as Kepler, precise mass and radius values as well as accurate information of evolutionary...

We present [OIII]{lambda}5007 fluxes and angular diametres for 435 Planetary Nebulae (PNe) in the central 10{deg}x10{deg} region towards the Galactic bulge. Our sample is taken...

The Wide Angle Search for Planets (WASP) survey currently operates two installations, designated SuperWASP-N and SuperWASP-S, located in the Northern and Southern hemispheres,...

The SuperWASP-I (Wide Angle Search for Planets-I) instrument observed 6.7 million stars between 8 and 15mag from La Palma during the 2004 May-September season. Our...

We have performed photometric observations of nearly seven million stars with 8

A new catalog of eclipsing binary stars with eccentric orbits is presented. The catalog lists the physical parameters (including apsidal motion parameters) of 124 eclipsing...

We have compiled the well-determined absolute parameters of Algol-type binaries. The lists contain the parameters of 74 detached and 61 semi-detached close binaries. The...

A catalogue of close eclipsing binary systems (detached and semidetached) with at least one of the components located in the delta Scuti region of the Cepheid instability strip...

In the third APOKASC catalog, we present data for the complete sample of 15,808 evolved stars with APOGEE spectroscopic parameters and Kepler asteroseismology. We used 10...
