A peculiar galaxy appears at redshift 11: properties of a moderate redshift interloper
Matthew Hayes, Nicolas Laporte, Roser Pello +2
Laporte et al. (2011) reported a very high redshift galaxy candidate: a lensed J-band dropout (A2667-J1). J1 has a photometric redshift of z=9.6-12, the probability density functio…
The all-sky GEOS RR Lyr survey with the TAROT telescopes. Analysis of the Blazhko effect
J. -F. Le Borgne, A. Klotz, E. Poretti +9
We used the GEOS database to study the Blazhko effect of galactic RRab stars. The database is continuously enriched by maxima supplied by amateur astronomers and by a dedicated sur…
Evolutionary changes in the periods of galactic RRab stars
Jacqueline Vandenbroere, Ennio Poretti, Jean-Francois Le Borgne
Le Borgne et al. (2007) report on the determination of evolutionary changes in the periods of field RR Lyr stars. Thanks to the extension of the GEOS database, we could analyze a s…
