Plaskett's Star: Analysis of the CoRoT photometric data
Plaskett's Star the CoRoT photometric data
2011/1/10
The SRa02 of the CoRoT space mission for Asteroseismology was partly devoted to stars belonging to the Mon OB2 association. An intense monitoring was performed on Plaskett's Star (HD47129) and the unp...
The Supernova Legacy Survey 3-year sample: Type Ia Supernovae photometric distances and cosmological constraints
The Supernova Legacy Survey 3-year sample Type Ia Supernovae photometric distances
2011/1/10
We present photometric properties and distance measurements of 252 high redshift Type Ia supernovae (0.15 < z < 1.1) discovered during the first three years of the Supernova Legacy Survey (SNLS). Thes...
Photometric variability of the Be star CoRoT-ID 102761769
Photometric variability the Be star CoRoT-ID
2011/1/11
Classical Be stars are rapid rotators of spectral type late O to early A and luminosity class V-III, wich exhibit Balmer emission lines and often a near infrared excess originating in an equatorially ...
A mid-term astrometric and photometric study of Trans-Neptunian Object (90482) Orcus
A mid-term astrometric photometric study
2011/1/13
From CCD observations of a fixed and large star field that contained the binary TNO Orcus, we have been able to derive high-precision relative astrometry and photometry of the Orcus system with respec...
Identification of strong photometric activity in the components of LHS 1070
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/27
Activity in low-mass stars is an important ingredient in the evolution of such objects. Fundamental physical properties such as age, rotation, magnetic field are correlated with activity.
Photometric study of two beta Cephei pulsators in eclipsing systems
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/24
We present results of a photometric study of the young southern open cluster Stock 14. This cluster is known to contain two eclipsing systems with presumed beta Cephei components, HD 101794 and HD 101...
Statistical Classification Techniques for Photometric Supernova Typing
Cosmology and Extragalactic Astrophysics (astro-ph.CO) Applications (stat.AP)
2010/12/24
Future photometric supernova surveys will produce vastly more candidates than can be followed up spectroscopically, highlighting the need for effective classification methods based on lightcurves alon...
Photometric Modelling of Close Binary Star CN And
Close binaries stars spot active starts light curve
2010/9/17
The results of two color photometry of active close binary CN And are presented and analyzed. The light curves of the system are obviously asymmetric, with the primary maximum brighter than the second...
