An analysis of Bordeaux meridian transit circle observations of planets and satellites (1997-2007)
Context. Meridian transit circle observations of the planets and their satellites are regularly performed for ephemerides improvement. Some have been made in Bordeaux observatory during the period 1997-2007. Aims. This paper presents these observations and makes an analysis of the data in order to determine the accuracy of the observations, their interest for dynamical purpose and a comparison ...

ASCA X-ray observations of the super-metal-rich stars 30 Ari and η Boo
We present X-ray observations of two late-type stars, HR 764 (30 Ari B, F4V) and HR 5235 (η Boo, G0IV), with photospheric metal abundances about twice the solar value. We have derived the coronal temperatures and metallicities of these stars, and compared them with those of other stellar X-ray sources with solar or sub-solar photospheric composition, already observed with ROSAT and ASCA. The X-...
متن کاملObservations of Pulsating Stars
Pulsations discussed will begin at the “top” of the instability strip with pulsating red giants and Miras, which are evolved stars nearing their own demise. The next discussed will be the Cepheids, both the “Classical” ones as well as the W Virginis (Population II stars). While moving down the instability strip of the HR Diagram, the next major type of variable (pulsating) star are the RR Lyrae...
