(MgAl2O4)n and (CaAl2O4)n, n=1-7 clusters data
Spinel (MgAl_2_O_4_) and krotite (CaAl_2_O_4_) are alternative candidates to alumina (Al_2_O_3_) as primary dust condensates in the atmospheres of oxygen-rich evolved stars.... -
Radial velocity of southern visual multiple stars
High-resolution spectra of visual multiple stars were taken in 2008-2009 to detect or confirm spectroscopic subsystems and to determine their orbits. Radial velocities of 93... -
PTPS stars IV.
Our knowledge of the intrinsic parameters of exoplanets is as precise as our determinations of their stellar hosts parameters. In the case of radial velocity searches for... -
3D non-LTE Balmer line formation
Hydrogen Balmer lines are commonly used as spectroscopic effective temperature diagnostics of late-type stars. However, reliable inferences require accurate model spectra, and... -
C and O isotopic ratios in Arcturus and Aldebaran
We re-analyzed the carbon and oxygen isotopic ratios in the atmospheres of the two bright K giants Arcturus ({alpha} Boo) and Aldebaran ({alpha} Tau). These stars are in the... -
Radial velocity curve of HD 189733
Extra-solar planet search programs require high-precision velocity measurements. They need to study how to disentangle radial-velocity variations due to Doppler motion from the... -
IR observations of S stars
Photometric observations in the near infrared for 161 S stars, including 18 Tc-rich (intrinsic) stars, 19 Tc-deficient (extrinsic) ones and 124 candidates for Tc-deficient S...
