Validating post-AGB candidates in the LMC and SMC using SALT spectra
Ryszard Szczerba, Marcin Hajduk, Yakiv V. Pavlenko +8
We selected a sample of post-AGB candidates in the Magellanic Clouds on the basis of their near- and mid-infrared colour characteristics. Fifteen of the most optically bright post-…
Metallicity, temperature, and gravity scales of M subdwarfs
N. Lodieu, F. Allard, C. Rodrigo +5
The aim of the project is to define a metallicity/gravity/temperature scale vs spectral types for metal-poor M dwarfs. We obtained intermediate-resolution ultraviolet (R~3300), opt…
Spectroscopic variability of IRAS22272+5435
L. Začs, F. Musaev, B. Kaminsky +4
A time series of high-resolution spectra was observed in the optical wavelength region for the bright proto-planetary nebula IRAS22272+5435 (HD235858), along with a simultaneous mo…
Unusual quasars from the Sloan Digital Sky Survey selected by means of Kohonen self-organising maps
H. Meusinger, P. Schalldach, R. -D. Scholz +4
We exploit the spectral archive of the Sloan Digital Sky Survey (SDSS) Data Release 7 to select unusual quasar spectra. The selection method is based on a combination of the power…
Modelling the spectrum and SED of V838 Mon
Ya. Pavlenko, B. Kaminsky, Yu. Lyubchik +1
We model the spectra and spectral energy distribution of V838 Mon which were observed in February, March, and November, 2002. Theoretical spectra are calculated using the classical…
