The Asiago Transient Classification Program (Tomasella et al. 2014, AN, 335, 841) reports the spectroscopic classification
of the following transients. Targets were supplied by the Astronomy Section of the Rochester Academy of Sciences (arXiv:1103.5165) and by the CBAT Transient Objects Confirmation Page (TOCP).
The observations were performed with the Asiago 1.82 m Copernico Telescope
(+AFOSC; range 340-820 nm; resolution 1.2 nm), which was equipped with a new CCD
(Andor IKON L936) with higher response both in the UV and in the NIR.
Name | Date (UT) | z | Type | Phase | Notes
PSN J10483231+2635179 | 20141218.18 | 0.021 | Ia | pre max | (1)
(1) A good match is found with several normal type-Ia supernovae few days before B-band maximum light.
The expansion velocity of PSN J10483231+2635179 (= CSS141215:104832+263518),
as deduced from the position of the minimum of the Si-II 635.5nm absorption,
is around 14400 km/s.
Classification was done with GELATO (Harutyunyan et al. 2008, A&A, 488, 383) and SNID (Blondin and Tonry 2007, ApJ, 666, 1024).
