We report the following classifications of optical transients from spectroscopic observations with the KOSMOS
on the Mayall telescope. Targets were supplied by the Pan-STARRS Survey for Transients (PSST). All observations were made
on 2015 April 20 UT. Classifications were performed with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024).
Name | RA (J2000) | Dec (J2000) | z | Type | Phase | Notes
PS15ade | 16:09:01.41 | +34:26:24.6 | 0.09 | Ia | +5d | (1)
PS15adh | 13:30:32.07 | -00:44:04.5 | 0.102 | Ia | -3d |
PS15ado | 09:50:11.57 | -05:57:49.0 | 0.11 | Ia | +3d | (2)
Notes:
When the redshift is given to 2 decimal places, it is derived from the SN spectrum. Otherwise, the redshift is determined from the host galaxy.
(1)91T-like spectrum
(2)The light-curve is rising.
