Metallicity estimation of RR Lyrae stars from their I-band light curves
István Dékány, Eva K. Grebel, Grzegorz Pojmański
We have revisited the problem of metallicity prediction of RR Lyrae stars from their near-infrared light curves in the Cousins I waveband. Our study is based on high-quality time-s…
An Asymmetric Eclipse Seen Towards the Pre-Main Sequence Binary System V928 Tau
Dirk van Dam, Matthew Kenworthy, Trevor David +21
K2 observations of the weak-lined T Tauri binary V928 Tau A+B show the detection of a single, asymmetric eclipse which may be due to a previously unknown substellar companion eclip…
Optical, UV, and X-Ray Evidence for a 7-Year Stellar Cycle in Proxima Centauri
B. J. Wargelin, S. H. Saar, G. Pojmański +2
Stars of stellar type later than about M3.5 are believed to be fully convective and therefore unable to support magnetic dynamos like the one that produces the 11-year solar cycle.…
Orbital and physical parameters of eclipsing binaries from the ASAS catalogue - VIII. The totally-eclipsing double-giant system HD 187669
K. G. Hełminiak, D. Graczyk, M. Konacki +14
We present the first full orbital and physical analysis of HD 187669, recognized by the All-Sky Automated Survey (ASAS) as the eclipsing binary ASAS J195222-3233.7. We combined mul…
A new look at the long-period eclipsing binary V383 Sco
Cezary Gałan, Toma Tomov, Taichi Kato +9
V383Sco was discovered to be an eclipsing binary at the beginning of the XX century. This system has one of the longest orbital periods known (13.5yr) and was initially classified…
Discovery of the 2010 Eruption and the Pre-Eruption Light Curve for Recurrent Nova U Scorpii
Bradley E. Schaefer, Ashley Pagnotta, Limin Xiao +12
We report the discovery by B. G. Harris and S. Dvorak on JD 2455224.9385 (2010 Jan 28.4385 UT) of the predicted eruption of the recurrent nova U Scorpii (U Sco). We also report on…
Photometric variability of the T Tauri star TW Hya on time scales of hours to years
Slavek M. Rucinski, Jaymie M. Matthews, Rainer Kuschnig +7
MOST (Microvariability & Oscillations of STars) and ASAS (All Sky Automated Survey) observations have been used to characterize photometric variability of TW Hya on time scales fro…
