Photometry of two unusual A supergiant systems in the Small Magellanic Cloud
R. E. Mennickent, M. Smith, Z. Kołaczkowski +2
We present multiwavelength broadband photometry and V, I time resolved photometry for two variable bright stars in the SMC, OGLE004336.91-732637.7 (SMC-SC3) and OGLE004633.76-73120…
A study of the interacting binary V 393 Scorpii
R. E. Mennickent, Z. Kolaczkowski, D. Graczyk +1
We present high resolution J-band spectroscopy of V 393 Sco obtained with the CRIRES at the ESO Paranal Observatory along with a discussion of archival IUE spectra and published br…
Frequency analysis of Cepheids in the Large Magellanic Cloud. New types of classical Cepheid pulsators
P. Moskalik, Z. Kolaczkowski
We have performed a detailed systematic search for multiperiodicity in the Population I Cepheids of the Large Magellanic Cloud. In this process we have identified for the first tim…
Double Mode Cepheids with Amplitude Modulation
P. Moskalik, Z. Kolaczkowski, T. Mizerski
Recent search for multiperiodicity in LMC Cepheids (Moskalik, Kolaczkowski & Mizerski 2004) has led to discovery of periodic modulation of amplitudes and phases in many of the firs…
High-amplitude Delta Scuti stars in the Galactic bulge from the OGLE-II and MACHO data
A. Pigulski, Z. Kolaczkowski, T. Ramza +1
Searching for main-sequence pulsators, we analyzed photometry of ~200,000 variable star candidates from the OGLE-II Galactic fields, finding 193 high-amplitude Delta Scuti stars. T…
