How peculiar is the “ peculiar variable ” DZ Crucis ( Nova Cru 2003 ) ?
The variable star DZ Cru was thought to be a nova when it was discovered in eruption in 2003 August. This explanation was later challenged, however, when the first spectra of the object were reported. We present near infrared spectroscopy of DZ Cru obtained at the New Technology Telescope on 3 occasions, starting ∼ 1.5 years after outburst, with the aim of establishing the nature of the object....
متن کاملThe Peculiar 2004 Superoutburst in the Helium Dwarf Nova , 2003 aw
We conducted a time-resolved photometric campaign of the helium dwarf nova, 2003aw in 2004 May– June. 2003aw stayed at 14.7–15.7 mag for the first several days during this campaign, which is the plateau phase of this superoutburst. This variable then rapidly decayed to ∼18.0 mag, still brighter by about 2 mag than its quiescence magnitude, and maintained this brightness for about 20 days, havin...
متن کاملThe circumstellar dust shell ?
A spherically symmetric dust radiative transfer code is used to model the circumstellar dust shell around IRC +10 216. Compared to numerous previous models a much larger body of observational data is used as constraints; the spectral energy distribution between 0.5 and 60000 µm, 2-4 µm and 8-23 µm spectra, optical, far-infrared and centimeter sizes and interferometric visibility curves between ...
متن کاملDUST FORMATION AND He II λ4686 EMISSION IN THE DENSE SHELL OF THE PECULIAR TYPE Ib SUPERNOVA 2006jc
We present evidence for the formation of dust grains in an unusual Type Ib supernova (SN) based on late-time spectra of SN 2006jc. The progenitor suffered an outburst qualitatively similar to those of luminous blue variables (LBVs) just 2 yr prior to the SN, and we propose that the dust formation is a consequence of the SN blast wave overtaking that LBV-like shell. The key evidence for dust for...
متن کاملThe Nova Shell and Evolution of the Recurrent Nova T Pyxidis
T Pyxidis is the prototypical recurrent nova (RN) with five eruptions from 1890 to 1967 and a mysterious nova shell. We report here on new observations of the nova shell with the Hubble Space Telescope (HST) in the year 2007, which provides a long time baseline from earlier HST images in 1994 and 1995. We find that the knots in the nova shell are expanding with velocities ranging from roughly 5...
