Constraining the degree of the dominant mode in QQ Vir

Andrzej Baran, John Telting, Roy Ostensen +9

We present early results of the application of a method which uses multicolor photometry and spectroscopy for \ell discrimination. This method has been successfully applied to the…

The pulsating hot subdwarf Balloon 090100001: results of the 2005 multisite campaign

A. Baran, R. Oreiro, A. Pigulski +28

We present the results of a multisite photometric campaign on the pulsating sdB star Balloon 090100001. The star is one of the two known hybrid hot subdwarfs with both long- and sh…

A massive binary black-hole system in OJ287 and a test of general relativity

M. J. Valtonen, H. J. Lehto, K. Nilsson +23

Tests of Einstein's general theory of relativity have mostly been carried out in weak gravitational fields where the space-time curvature effects are first-order deviations from Ne…

The new sample of giant radio sources II. Update of optical counterparts, further spectroscopy of identified faint host galaxies, high-frequency radio maps, and polarisation properties of the sources

J. Machalski, M. Jamrozy, S. Zola +1

Our sample of giant radio-source candidates, published in Paper I (Machalski et al. 2001), is updated and supplemented with further radio and optical data. In this paper we present…

Multicolour photometry of Balloon 090100001: linking the two classes of pulsating hot subdwarfs

A. Baran, A. Pigulski, D. Koziel +3

We present results of the multicolour UBVR photometry of the high-amplitude EC14026-type star, Balloon 090100001. The data span over a month and consist of more than a hundred hour…
