We performed elemental abundances analyses of the mercury-manganese (HgMn) stars 53 Tau, {beta} Tau, and {gamma} Crv consistent with previous studies of similar stars in this... -
CCD photometry in 6 open clusters
Within the sample of six young open clusters (NGC 1502, NGC 3105, Stock 16, NGC 6268, NGC 7235 and NGC 7510) we have investigated 1753 objects using the narrow band, three... -
{Delta}a photometry of CP stars
We have summarized all {Delta}a measurements for galactic field stars (1474 objects) from the literature published over more than two decades. These measurements were, for the... -

Differential Stroemgren uvby observations from the Four College Automated Photoelectric Telescope are presented for the magnetic CP (mCP) stars HR 2258, MW Vul, and HR 9017 and... -
Emission lines in optical spectrum of 3 Cen A
Weak emission lines in the optical spectrum of the helium-weak chemically peculiar star 3 Cen A are tabulated. The observed wavelengths, line identification information and... -
Catalogue of stellar effective magnetic fields
We present the catalogue of averaged quadratic effective magnetic fields for 596 main sequence and giant stars. The catalogue is derived from measurements of the stellar... -
Elemental abundances of three CP stars
We used data from the EBASIM spectrograph of the 2.1-m CASLEO telescope to study three rather sharp-lined late B to early A stars {xi} Oct (B6 IV), {alpha} Sex (B9.5 III), and... -
Elemental abundances of four A-B stars
The superficially normal stars {theta} And (A2 V), {epsilon} Del (B6 III), {epsilon} Aqr (A1.5 V), and {iota} And (B9 V), which have rotationally broadened line profiles, are... -

JHKL' photometry of AGB stars
Multi-epoch near-infrared photometry for a sample of long period variables (SR, L, Mira). Data have been obtained at the Observatorio del Teide using the 1.5m "Carlos Sanchez... -
Non-LTE Ga abundance in HgMn stars
We present, for the first time, the Non-LTE gallium equivalent widths for the most prominent gallium transitions as identified in real spectra and in (hot) mercury-manganese... -
uvby{beta} photometry of lambda Bootis stars
Lambda Bootis stars comprise only a small number of all A-type stars and are characterized as nonmagnetic, Population I, late B to early F-type dwarfs which show significant... -
CCD {Delta}a-photometry of NGC 1866
We report on the detection of the first extragalactic, classical chemically peculiar (CP) stars more than 100 years after the discovery of this group. Using the tool of CCD... -
