Type II and anomalous Cepheids in the Kepler K2 mission
Monika I. Jurkovic, Emese Plachy, László Molnár +4
We present the results of the analysis of Type II and anomalous Cepheids using the data from the Kepler K2 mission. The precise light curves of these pulsating variable stars are t…
Spectroscopy of the massive interacting binary UU Cassiopeiae
P. Hadrava, M. Cabezas, G. Djurašević +9
Context. The eclipsing close binary UU Cas is an interacting massive double-periodic system with a gainer star partly hidden in an accretion disk. Aims. In order to study the physi…
BVRI Photometric Calibration of the Nedeljković Telescope
Ana Vudragović, Monika I. Jurković
We have done photometric calibration of the 60 cm Nedeljković telescope equipped with FLI PL 230 CCD camera, mounted at the Astronomical Station Vidojevica (Serbia), using standard…
TESS observations of Cepheid stars: first light results
E. Plachy, A. Pál, A. Bódi +33
We present the first analysis of Cepheid stars observed by the TESS space mission in Sectors 1 to 5. Our sample consists of 25 pulsators: ten fundamental mode, three overtone and t…
New insights on the massive interacting binary UU Cassiopeiae
R. E. Mennickent, G. Djurašević, I. Vince +7
We present the results of the study of the close binary UU Cassiopeiae based on previously published multi wavelength photometric and spectroscopic data. Based on eclipse timings o…
Anomalous Cepheids discovered in a sample of Galactic short period Type II Cepheids
Monika I. Jurkovic
We revisited the short period Type II Cepheids (T2Cs), called the BL Herculis (BLHs), in the Galactic Field to derive a homogeneous analysis of their Fourier parameters. Only V-ban…
The period-luminosity and period-radius relations of Type II and anomalous Cepheids
Martin A. T. Groenewegen, Monika Jurkovic
Method: In an accompanying paper (arXiv: 1705.00886) we determined luminosity and effective temperature for the 335 T2Cs and ACs in the LMC and SMC discovered in the OGLE-III surve…
Luminosities and infrared excess in Type II and anomalous Cepheids in the Large and Small Magellanic Clouds
Martin Groenewegen, Monika Jurkovic
(abridged) Type II and anomalous Cepheids (ACs) are useful distance indicators when there are too few classical Cepheids or when RR Lyrae stars are too faint. We study the sample o…
First observations of W Virginis stars with K2: detection of period doubling
E. Plachy, L. Molnár, M. I. Jurkovic +5
We present the first analysis of W Vir stars observed by the Kepler space telescope in the K2 mission. Clear cycle-to-cycle variation were detected in the light curves of KT Sco an…
Galactic membership of BL Her type variable stars
Monika I. Jurkovic, Milan Stojanović, Slobodan Ninković
As the RR Lyrae stars evolve on the Hertzsprung-Russell diagram they are believed to become short period Type II Cepheids, known as BL Her type (with a pulsation period from to…
On calibration of some distance scales in astrophysics
B. Vukotic, M. Jurkovic, D. Urosevic +1
We present a method for distance calibration without using standard fitting procedures. Instead we use random resampling to reconstruct the probability density function (PDF) of ca…
Pulsation and orbit of AU Pegasi
M. Jurkovic, L. Szabados, J. Vinkó +1
AU Pegasi is a pulsating star in a spectroscopic binary system with an orbital period of 53.26 days. Between 1960 and 1990 an extremely rapid period increase was observed in the va…
