Binarity and multiperiodicity in high-amplitude delta Scuti stars
A. Derekas, L. L. Kiss, T. R. Bedding +10
We have carried out a photometric and spectroscopic survey of bright high-amplitude delta Scuti (HADS) stars. The aim was to detect binarity and multiperiodicity (or both) in order…
Determination of the size, mass, and density of "exomoons" from photometric transit timing variations
A. Simon, K. Szatmary, G. M. Szabo
Precise photometric measurements of the upcoming space missions allow the size, mass, and density of satellites of exoplanets to be determined. Here we present such an analysis usi…
RR Lyrae stars in the southern globular cluster NGC 362
P. Szekely, L. L. Kiss, R. Jackson +3
NGC 362 is a bright southern globular cluster for which no extensive variability survey has ever been done. Time-series CCD photometric observations have been obtained. Light curve…
Possibility of a photometric detection of "exomoons"
Gy. M. Szabo, K. Szatmary, Zs. Diveki +1
We examined which exo-systems contain moons that may be detected in transit. We numerically modeled transit light curves of Earth-like and giant planets that cointain moons with 0.…
A first-overtone RR Lyrae star with cyclic period changes
A. Derekas, L. L. Kiss, A. Udalski +2
A detailed light curve analysis is presented for a first-overtone RR Lyrae star, MACHO* J050918.712-695015.31, based on MACHO and OGLE-III observations. As a foreground object of t…
A photometric monitoring of bright high-amplitude delta Scuti stars. II. Period updates for seven stars
A. Derekas, L. L. Kiss, P. Szekely +10
We present new photometric data for seven high-amplitude delta Scuti stars. The observations were acquired between 1996 and 2002, mostly in the Johnson photometric system. For one…
