Outburst Photometry of the Eclipsing Dwarf Nova GY Cancri
We observed the ROSAT-selected eclipsing dwarf nova GY Cnc (=RX J0909.8+1849) during the 2001 November outburst. We refined the orbital period to be 0.17544251(5) d. The fading portion of the outburst was indistinguishable from those of typical dwarf novae with similar orbital periods. However, the signature of orbital humps (or a hot spot) was far less prominently observed in the orbital light...
متن کاملSpitzer Space Telescope Observations of Var Her 04: Possible Detection of Dust Formation in a Superoutbursting Tremendous Outburst Amplitude Dwarf Nova
We present four MIPS (24 m) and two IRAC (3.6, 4.5, 5.8, and 8.0 m) Spitzer Space Telescope observations of the newly discovered tremendous outburst amplitude dwarf nova (TOAD) Var Her 04 during decline from superoutburst. The four MIPS observations span 271 days, and the two IRAC observations span 211 days. Along the line of sight to Var Her 04, there is a foreground M star within 100 of the v...
متن کاملV5116 Sgr, an Eclipsing Supersoft Post-outburst Nova?
months after the optical outburst. The X-ray spectrum shows that the nova had evolved to a pure supersoft X-ray source, with no significant emission at energies above 1 keV. The X-ray light-curve shows abrupt decreases and increases of the flux by a factor ∼ 8. It is consistent with a periodicity of 2.97 h, the orbital period suggested by Dobrotka et al. (2007), although the observation lasted ...
متن کاملOph ( Nova Oph 2002 ) : LARGE - AMPLITUDE SLOW NOVA WITH STRONG POST - OUTBURST OSCILLATIONS
V2540 Oph (Nova Oph 2002) was independently discovered by Katsumi Haseda and Yuji Nakamura at magnitude 9.0 on 2002 January 24 (Haseda et al. 2002). Retter et al. (2002) detected emission lines of hydrogen and Fe II, indicating that the object is an Fe II class nova caught in the early decline stage. Later examination of photographs revealed that the nova was already at magnitude 8.9 on 2002 Ja...
متن کاملSpectroscopic study of bright photometric candidates ⋆
We present medium-resolution spectroscopy of a sample of stars in the second Galactic quadrant selected from the literature because their colours suggest that they are moderately-reddened early-type stars at very large distances. From the derived spectral types and observed colours, we calculate distances to all these objects. For a sizable fraction of our sample, we find distances well in exce...
