| Abstract: |
We present the discovery of the brightest short period sdB pulsator found to
date, GALEX J06398+5156. With a V-band magnitude of 11.99 it outshines
even Balloon 090100001. The object was observed spectroscopically by Vennes et al. (2011), who determined an effective temperature of 30,750 K,
surface gravity of 5.70 and log(He/H) = –2.59. Here we present the first
results of an analysis of the photometric campaign organized in spring 2011
over one month with four different telescopes. |
