Identification of Dahlmark variables
The amateur observer Lennart Dahlmark has published a useful series of IBVS notes listing a number of candidate variable stars, most of which were new. Although adequate charts... -
Walraven photometry of WX Hyi
The SU UMa-type dwarf nova WX Hyi was observed in the 5 passbands VBLUW (544, 430, 384, 362 and 324nm) during 15 nights on the 90cm telescope at ESO (La Silla), between July and... -
VBLUW Observations of TT Ari
TT Ari was observed in the 5 passbands VBLUW (544, 430, 384, 362 and 324nm) during 3 nights on the 90cm telescope at ESO (La Silla), between July and November 1988, with an... -

Radio emission from stars at 250GHz
We have used the IRAM 30 m-telescope together with the Max Planck Institute for Radio Astronomy (MPIfR) bolometer to survey nearly 270 stars of different types for 250GHz... -

Study of star V9 in 47 Tuc
We present an infrared K-band light curve and a radial velocity curve for the RR Lyrae star V9 in the metal rich globular cluster 47 Tucanae ([Fe/H]=-0.71). Combining these new... -

Semiregular variables H2O maser
107 semiregular variables of spectral type M have been observed in the H2O 6(16)-5(23) line at 22.235GHz with the 100m Effelsberg radio telescope and maser emission has been... -
OH maser from semiregular variables
We have made a high sensivity (~0.15Jy) search in the OH main-lines for maser emission from a sample of 181 semiregular variables. -
[Fe/H] from RR Lyrae light curves
We present an accurate and robust method for the calculation of [Fe/H] from the light curves of RRab stars. The method introduces a considerable improvement relative to our... -
Long period Cepheids
The light curves of 124 classical Cepheids with period longer than 8 days were Fourier decomposed with the aim of detecting resonance effects between pulsation modes in the... -
Photometric & visibility data of IRC +10 216
A spherically symmetric dust radiative transfer code is used to model the circumstellar dust shell around IRC +10 216. Compared to numerous previous models a much larger body of... -
Miras temperatures, distances & magnitudes
Effective temperatures are determined for a sample of 165 oxygen-rich Miras using indices related to molecular band strength of titanium oxide and vanadium oxide. Using a...
