A remarkable long-term light curve, and deep, low-state spectroscopy: Swift & XMM-Newton monitoring of the NLS1 galaxy Mkn 335
remarkable long-term light curve low-state spectroscopy Swift XMM-Newton monitoring the NLS1 galaxy
2012/2/23
The Narrow-line Seyfert 1 galaxy (NLS1) Mkn 335 is remarkable because it has repeatedly shown deep, long X-ray low-states which show pronounced spectral structure. It has become one of the prototype A...
Light Curve Analysis of Hipparcos Data for the Massive O-type Eclipsing Binary UW CMa
Light Curve Hipparcos Data Binary UW CMa
2010/11/11
Hipparcos photometric data for the massive O-type binary UWCMa were analysed within the framework of the Roche model. Photometric solutions were obtained for five mass ratios in the q = M2/M1 = 0.5 &#...
Light Curve Solutions of Eclipsing Binaries in SMC
eclipsing binaries light curves modeling Small Magellanic Cloud global parameters
2010/11/12
We propose a procedure for light-curve solution of eclipsing bi-nary stars in the Small Magellanic Cloud for which photometric data have been obtained in the framework of the OGLE project as well as w...
A Revised Historical Light Curve of Eta Carinae and the Timing of Close Periastron Encounters
Solar and Stellar Astrophysics (astro-ph.SR) High Energy Astrophysical Phenomena (astro-ph.HE)
2011/1/7
The historical light curve of the 19th century "Great Eruption" of etaCar provides a striking record of violent instabilies encountered by the most massive stars. We report and analyze newly uncovered...
Photometric Observation and Light Curve Analysis of Binary System ER-Orionis
Photoelectric photometry—eclipsing binaries—overcontact systems
2010/9/15
Photometric observations of the over-contact binary ER ORI were performed during November 2007 and February to April 2008 with the 51 cm telescope of Biruni Observatory of Shiraz University in U, B an...

LIGHT CURVE ANALYSIS OF THE LATE TYPE BINARY V523 CASSIOPEIAE
binaries: close binaries: eclipsing Stars: individual: V523 Cas Stars: late-type Stars: activity
2010/10/29
We present the analysis of V and R light curves of the late type contact binary V523 Cas for the season of 2006. These observations make part of the monitoring program aimed at studying the long-term ...
