The STIS spectrograph on HST was used to obtain a spectrum of the white dwarf star Procyon B. Procyon B is a challenging object because it is a close binary companion of the 1st magnitude star Procyon A. In the spring of 1998, Procyon B was near apastron (approximately 5 arc sec from...
We present our preliminary results of the modelling of the F5 star Procyon A. The frequencies predicted by our models are compared with the frequencies extracted through a global fit to the power spectrum obtained by the latest ground-based observations, which provides two different mode ...
The Fourier transform spectrometer based at the CFH telescope was used as a stellar accelerometer in a new seismometric mode. One fringe at a selected path difference of the interferogram produced by the flux of a star through a bandpass chosen in the near infrared is continuously scanned. Its...
We compare the simultaneous 2007 space-based MOST photometry and ground-based radial velocity (RV) observations of the F5 star Procyon. We identify slow variations in the MOST data that are similar to those reported in the RV time series and confirm by comparison with the Sun that these variat...

We do not detect any significant excess in the power spectrum near 1 mHz. A limit on the amplitude of the modes can be deduced, which cannot exceed 1 m s(-1) . However, the ``comb response'' exhibits the signature of a possible regular pattern with a large splitting nu_0 of 53 ...
