1993 Superoutburst of LL Andromedae

The Planetary System of Upsilon Andromedae

The bright F8 V solar-type star upsilon Andromedae has recently been reported to have a system of three planets of Jovian masses. In order to investigate the orbital stability and mutual gravitational interactions among these extrasolar planets, both forward and backward integrations from the latest observed orbital elements for all three planets' orbits have been performed under the coplanar a...

EUVE Observations of OY Carinae in Superoutburst

The Extreme Ultraviolet Explorer (EUVE ) satellite was used for three days beginning on 1997 Mar 26.96 UT to obtain photometric and spectroscopic observations of the eclipsing SU UMa-type dwarf nova OY Carinae in superoutburst. Because of the longer time on source (143 ks), the larger number of eclipses observed (17), and the higher count rate in the detector (0.5–2.2 counts s), we are able to ...

EUVE Observations of VW Hydri in Superoutburst

EUVE observed the SU UMa-type dwarf nova VW Hydri in superoutburst for an interval of nearly 2 days in 1994 June and produced EUV light curves and the first EUV spectrum of this important CV. 1996, Cataclysmic Variables and Related Objects, ed. A. Evans & J. H. Wood (Dordrecht: Kluwer), 243

The Dwarf Nova Pq Andromedae

The Light Curve of S Andromedae

Historical observations of S And, in combination with the color versus rateof-decline relationship for well observed SN 1991bg-like supernovae, are used to estimate a rate of decline ∆m15 (B) = 2.21 and an intrinsic color at maximum [B(0)− V (0)]o = 1.32 for SN 1885A.
