The Asiago Transient Classification Program (Tomasella et al. 2014, AN, 335,
841) reports the spectroscopic classification of MASTER OT J044212.20+230616.7
in PGC 1681539 (ATel #6484).
The observation was performed with the Asiago 1.82 m Copernico Telescope
(+AFOSC; range 340-820 nm; resolution 1.2 nm).
Name | Date (UT) | z | Type | Phase | Notes
MASTER OT J044212.20+230616.7 | 20140923.08 | 0.016 | IIn/Ia-CSM | +60 d |
The spectrum is very similar to that of the type IIn/Ia-CSM SN 2005gj at about
2 month after maximum. The only remarkable difference is a broad and strong
P-Cygni feature consistent with NaID/He I 587.6nm. The emission component,
having a FWHM~9500 km/s, largely overwhelms the blue-shifted shallow
Classification was done with GELATO (Harutyunyan et al. 2008, A&A, 488, 383).
