Towards Asteroseismology of PG1605+072
A. Tillich, U. Heber, S. J. O'Toole +2
We present our attempt to characterise the frequency spectrum of the bright V 361 Hya star PG1605072 from atmospheric parameter and radial velocity variations through a spectros…
Six New ZZ Ceti Stars from the SPY and the HQS Surveys
B. Voss, D. Koester, R. Østensen +3
We report on the discovery of six new ZZ Ceti stars. They were selected as candidates based on preparatory photometric observations of objects from the Hamburg Quasar Survey (HQS),…
The O-C diagram of the subdwarf B pulsating star HS2201+2610: detection of a giant planet?
R. Silvotti, S. Schuh, R. Janulis +9
In this article we present the O-C diagram of the hot subdwarf B pulsating star HS2201+2610 after seven years of observations. A secular increase of the main pulsation period, Pdot…
Multiwavelength observations revealing the outbursts of the two soft X-ray transients XTE J1859+226 and XTE J1118+480
S. Chaty, C. A. Haswell, R. I. Hynes +9
We report here on multiwavelength observations of the two new soft X-ray transients (SXTs) XTE J1859+226 and XTE J1118+480, which we observed with HST/RXTE/UKIRT. For XTE J1118+480…
Three photometric methods tested on ground-based data of Q 2237+0305
I. Burud, R. Stabell, P. Magain +5
The Einstein Cross, Q~2237+0305, has been photometrically observed in four bands on two successive nights at NOT (La Palma, Spain) in October 1995. Three independent algorithms hav…
High resolution optical and near-IR imaging of the quadruple quasar RX J0911.4+0551
I. Burud, F. Courbin, C. Lidman +10
We report the detection of four images in the recently discovered lensed QSO RX J0911.4+0551. With a maximum angular separation of 3.1", it is the quadruply imaged QSO with the wid…
