Speckle interferometry of nearby multiple stars
We present the results of diffraction-limited optical speckle interferometry and infrared bispectrum speckle interferometry of 111 double and 10 triple systems performed in... -
CCD {Delta}a-photometry of 5 open clusters
In total, more than 550 objects within the fields of five open clusters (NGC 2439, NGC 3960, NGC 6134, NGC 6192 and NGC 6451) were investigated in order to find classical... -
Cepheids in Magellanic Clouds. II.
The analysis of CCD observations of ten new suspected second overtone mode Cepheids in the SMC does not confirm the nature of such stars; most of them appear to be first... -
HST VI photometry and proper motions in NGC 6528
Using two epochs of HST/WFPC2 images of the metal-rich globular cluster NGC 6528 we derive the proper motions of the stars and use them to separate the stars belonging to NGC... -
Search for duplicity in periodic Be stars
Four Be stars, HR 1960, HR 2968, HR 3237 and HR 3642, selected according to their periodic variations in Hipparcos and Geneva photometries, have been monitored from 1998 until... -
UBVI photometry of NGC 7036 and NGC 7772
We present CCD UBVI observations obtained in the field of the two previously unstudied dissolving open cluster candidates NGC 7036 and NGC 7772. Our analysis suggests that both... -
uvby{beta} photometry of early type stars
The {beta} Cephei stars and slowly pulsating B (SPB) stars are massive main sequence variables. The strength of their pulsational driving strongly depends on the opacity of... -
CoRoT 101155310 light curve
The continuous monitoring of ASAS 192647-0030.0=CoRoT 101155310 ensured from space by the CoRoT (Convection, Rotation and planetary Transits) mission allowed us to detect the... -
Radial velocities in the globular NGC 2808
The formation mechanism of hot horizontal branch (HB) stars is still one of the most uncertain points of stellar evolution theories. In the past decade, models based on their... -
Normalized spectra of 20 red giants
Accurate fundamental parameters of stars are mandatory for the asteroseismic investigation of the Kepler mission to succeed. We determine the atmospheric parameters for a sample... -
QSOs CaII absorbers
We present a systematic study of weak intervening CaII absorbers at low redshift (z<0.5), based on the analysis of archival high-resolution (R>=45000) optical spectra of... -
Synthetic lines in the Sun
We have computed synthetic spectra from a realistic 3D numerical simulation of the solar photosphere. We provide the spatially averaged spectra for selected lines that are... -
Radial velocities of HD 10180
Low-mass extrasolar planets are presently being discovered at an increased pace by radial velocity and transit surveys, which opens a new window on planetary systems. We are... -
GJ3634 radial velocity and 4.5um flux
We report on the detection of GJ3634b, a super-Earth of mass msini=7.0+/-0.9 Mearth and period P=2.64561+/-0.00066-day. Its host star is a M2.5 dwarf, has a mass of... -
