Dust formation in Nova Cephei 2013
Abstract
We report near-infrared K band photometry and spectroscopy of Nova Cephei 2013, discovered by K. Nishiyama and F. Kabashima on 2013 Feb 2.4 UT (cf. CBET #3397, ATel #4950, #4893, #5026). The observations were made using the 2-m Himalayan Chandra telescope (+TIFR Near Infrared Imager and Spectrometer, TIRSPEC) at the Indian Astronomical Observatory (IAO), Hanle (Ladakh). The estimated K band magnitudes of nova were: 2013 June 23 UT, 7.40 +/-0.02 and 2013 July 8 UT 7.84 +/- 0.02; the source brightness has therefore dimmed by 0.44 mag in K band during 16 days.
