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 ...
Spectral variability of quasars from multi-epoch photometric data in the Sloan Digital Sky Survey Stripe 82
Spectral variability multi-epoch photometric data
2011/1/11
We present a new approach to analysing the dependence of quasar variability on rest-frame wavelengths. We exploited the spectral archive of the Sloan Digital Sky Survey (SDSS) to create a sample of mo...
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...
Photometric Catalogue of Quasars and Other Point Sources in the Sloan Digital Sky Survey
astronomical data bases miscellaneous – catalogues – techniques pho-tometric – methods statistical – surveys
2010/11/12
We present a catalogue of about 8.6 million unresolved photometric detections in the Sloan Digital Sky Survey Seventh Data Release classifying them into stars, galaxies and quasars using a machine lea...
Photometric monitoring of Luminous Blue Variables
Photometric monitoring Luminous Blue Variables
2010/11/16
We present some preliminary results from our program of intensive near-infrared photometric monitoring of a sample of confirmed and candidate Luminous Blue Variables (LBVs) conducted from 2008 to 2010...
Galaxy clustering and projected density profiles as traced by satellites in photometric surveys: Methodology and luminosity dependence
Galaxy clustering projected density profiles photometric surveys
2010/11/12
We develop a new method which measures the projected density distribution wp(rp)n of photometric galaxies surrounding a set of spectroscopically-identified galaxies, and simultaneously the projected c...
Photometric redshifts for GRB afterglows from GROND and Swift/UVOT
gamma rays bursts Techniques photometric
2010/11/11
Aims. We present a framework to obtain photometric redshifts (photo-zs) for gamma-ray burst afterglows. Using multi-band photometry from GROND and Swift/UVOT, photo-zs are derived for five GRBs for wh...
