Masses & radii of 4 VLM stars in EB systems
Eclipsing binaries (EBs) with one of the companions as very low-mass stars (VLMSs; or M dwarfs) are testbeds to substantiate stellar models and evolutionary theories. Here we... -
Occurrence rates for Q1-Q16 KOI catalog planet cand.
We present a new framework to characterize the occurrence rates of planet candidates identified by Kepler based on hierarchical Bayesian modeling, approximate Bayesian computing... -
Abundances in the local region. III. Southern dwarfs
Stellar parameters and abundances have been derived from a sample of 907 F, G, and K dwarfs. The high-resolution, high signal-to-noise spectra utilized were acquired with the... -
Differential photometry of the F-subgiant HAT-P-67
We report the discovery of HAT-P-67b, which is a hot-Saturn transiting a rapidly rotating F-subgiant. HAT-P-67b has a radius of R_p_=2.085_-0.071_^+0.096^ R_J_, and orbites a... -
Abundances in the local region. II. F, G, and K dwarfs
Parameters and abundances have been derived for 1002 stars of spectral types F, G, and K, and luminosity classes IV and V. After culling the sample for rotational velocity and... -
Radial velocity of HD 33643
We report the discovery of KELT-7b, a transiting hot Jupiter with a mass of 1.28+/-0.18M_J_, radius of 1.533^+0.046^-0.047_R_J, and an orbital period of... -
A-F type variable stars from Kepler
The light curves of 2768 stars with effective temperatures and surface gravities placing them near the gamma Doradus ({gamma} Dor)/delta Scuti ({delta} Sct) instability region... -
From binaries to multiples. II. Statistical data
Statistics of hierarchical multiplicity among solar-type dwarfs are studied using the distance-limited sample of 4847 targets presented in the accompanying Paper I. Known facts... -
From binaries to multiples. I. The FG-67 sample
Data on the multiplicity of F- and G-type dwarf stars within 67pc of the Sun are presented. This distance-limited sample based on the Hipparcos catalog contains 4847 primary... -
Photometry and spectroscopy of HAT-P-49
We report the discovery of the transiting extrasolar planet HAT-P-49b. The planet transits the bright (V=10.3) slightly evolved F-star HD340099 with a mass of 1.54M_{Sun} and a... -
Atmospheric parameters in luminous stars
Parameters and abundances for 451 stars of spectral types F, G, and K of luminosity classes I and II have been derived. Absolute magnitudes and E(B-V) have been derived for the... -
Differential griz photometry of HATS-3
We report the discovery by the HATSouth survey of HATS-3b, a transiting extrasolar planet orbiting a V=12.4 F dwarf star. HATS-3b has a period of P=3.5479days, mass of... -
Abundances of late K and M dwarfs in binary systems
Knowledge of late K and M dwarf metallicities can be used to guide planet searches and constrain planet formation models. However, the determination of metallicities of... -
Follow-up photometry for HAT-P-34 through HAT-P-37
We report the discovery of four transiting extrasolar planets (HAT-P-34b-HAT-P-37b) with masses ranging from 1.05 to 3.33M_J_ and periods from 1.33 to 5.45days. These planets... -
Spitzer 24{mu}m photometry of Hipparcos F stars
We have conducted a study of debris disks around F stars in order to explore correlations between rotation, stellar winds, and circumstellar disks. We obtained new 24{mu}m... -

We present new grids of colors and bolometric corrections for F-K stars having 4000 K {<=} Teff {<=} 6500 K, 0.0 {<=} log(g) {<=} 4.5, and -3.0 {<=} [Fe/H]... -
Rotation and binary rate among giant F stars
We have tested the hypothesis of Berthet (1991A&A...251..171B) which foresees that Am stars become giant metallic A and F stars (defined by an enhanced value of the... -
Rotational velocities of F dwarfs
table4 contains rotational velocities for 177 dwarfs with spectral types between A7 en G2. -
Near-core rotation of intermediate-mass stars
The sparsely sampled time-series photometry from Gaia Data Release 3 (DR3) led to the discovery of more than 100000 main-sequence non-radial pulsators. The majority of these... -
A close outer companion to TOI-2109 b?
Hot Jupiters with close-by planetary companions are rare, with only a handful of them having been discovered so far. This could be due to their suggested dynamical histories,...
