MACHO r,b light curves of MC eclipsing binaries
We present a new sample of 4634 eclipsing binary stars in the Large Magellanic Cloud (LMC), expanding on a previous sample of 611 objects and a new sample of 1509 eclipsing... -
Radial velocities of southern close binaries
Radial velocity measurements and sine-curve fits to the orbital velocity variations are presented for nine contact binaries: V1464 Aql, V759 Cen, DE Oct, MW Pav, BQ Phe, EL Aqr,... -
UBV(RI) differential photometry of FI Boo
UBVR_C_I_C_ photometry of the W UMa eclipsing binary FI Bootis has been obtained and analyzed simultaneously with previously published photometry and radial velocities. The... -
V523 Cas UBVR_C_I_C_ photometry
The cool, overcontact, close binary, V523 Cassiopeiae was observed with the 1 m reflector at the US Naval Observatory, Flagstaff Station. The photometry was very good, with a... -
IVB mag of LMC ellipsoidal variables
We used the OGLE-II and OGLE-III photometry of red giants in the Large Magellanic Cloud to select and study objects revealing ellipsoidal variability. We detected 1546... -
VB light curves of YY Eri
The photoelectric observations in v and b bands for YY Eri are presented. These observations were obtained during four nights in November, 1984, with the 35-cm Cassegrain... -
Geneva photometry of the Algol system TZ Eri
Light curves of the semi-detached eclipsing binary system TZ Eridan in the Geneva 7-colour photometric system were analysed using the Wilson-Devinney programme. The physical and... -
AO Vel four-colour photometry

Radial velocities of UCAC4 721-037069
Large radial velocity variations in the LAMOST spectra of giant stars have been used to infer the presence of unseen companions. Some of them have been proposed as possible... -
HD27130 photometric light curves
The derivation of accurate and precise masses and radii is possible for eclipsing binary stars, allowing for insights into their evolution. When residing in star clusters, they... -
Bright B-type variables in Scorpius
The first two of a total of six nano-satellites that will constitute the BRITE-Constellation space photometry mission have recently been launched successfully. In preparation... -
CoRoT-100866999 frequency analysis
The presence of g- and p-modes allows testing stellar models from the core to the envelope. Moreover, binarity in an eclipsing system constrains the physical parameters of the... -
FGK dwarf stars limb darkening coefficients
Limb darkening is a fundamental ingredient for interpreting observations of planetary transits, eclipsing binaries, optical/infrared interferometry and microlensing events.... -
Light curves of CoRoT-2 in z-band, 4.5um and 8um
We report measurements of the thermal emission of the young and massive planet CoRoT-2b at 4.5 and 8um with the Spitzer Infrared Array Camera (IRAC). Our measured occultation... -
EW Ori differential uvby light curves
Recent studies of inactive and active solar-type binaries suggest that chromospheric activity, and its effect on envelope convection, is likely to cause significant radius and... -
Radial velocities of RZ Cas
In a first report on the results of a multi-site campaign in 2001 of photometric and spectroscopic observations of the active semi-detached Algol-type system RZ Cas, we... -
UBV light curves of V477 Cyg
New and complete UBV light curves and times of minimum are presented for the Algol type eclipsing binary V477 Cygni (Sp. A3V+F5V, m_v_=8.5, P=2.347days). The binary orbit of the... -
V436 Persei UBV photometry
An analysis of new spectroscopic and photoelectric UBV observations, satisfactorily covering the whole orbital period of V436 Per, together with existing data allowed us to... -
Long-term monitoring of SZ Cam
We present the results of the reduction of our photometric and spectroscopic observations for the eclipsing binary SZ Cam performed with the telescopes at the Astronomical... -
Close binary system BZ Mon
The results of a UBVR photometry observations and light curve analysis are presented for eclipsing binary, BZ Mon.
