Supernovae (SNe) are giant stellar explosions and excellent sources of metal enrichment in the
Universe. SNe are classified based on the presence/absence of hydrogen in their early spectra.
However, there are different sub-classes of hydrogen deficient SNe that exist within type Ia and Ib/c
SNe. The existence of various sub-classes of type Ia SNe are a great challenge to their uniformity and
demands a full characterisation of individual SNe both peculiar and normal. In this talk I will present
results and future work of a type Iax SN, SN 2014dt, which hints towards an incomplete eruption of a
white dwarf leaving behind a remnant. Such a remnant was earlier detected in only one other SN, SN
2008ha, in very late phase observations. I will discuss the similarities and dissimilarities of SN
2014dt (type Iax) and ASASSN-15so (type Ia) in terms of the photometric and spectroscopic
evolution. The other sub-class of hydrogen deficient SNe, type Ib, are of core collapse origin. In my
recent work I have indicated the plausible progenitors of two type Ib SNe (M12045 (single WR star)
and PS15bgt (binary system)). The spectroscopic observations of such events also confirms the
aspherical explosion geometry. In order to constrain the explosion geometry and identification of the
progenitor systems a systematic study of nearby type Ib/c SNe is required. We aim to fulfill the above
goals with the use of ARIES telescopes and other national/international observing facilities.
