SN 2010kd: a super-luminous supernova that exploded rapidly and decayed slowly

Part of: GS Prelims and GS-III – Space

In News:

Researchers at the Arayabhatta Research Institute of Observational Sciences (ARIES), Nainital recently carried out study of SN 2010kd
ARIES is an autonomous research institute under the Department of Science and Technology (DST), Govt. of India.

Key takeaways:

SN 2010kd is a super-luminous supernova which ejected huge amounts of mass and Nickel during explosion.
The amount of ejection was much more than seen in case of normal core-collapse supernovae, which indicates that the related star evolution might be different.
It exploded with a larger velocity but decayed slower than other similar supernovae.

Important value additions:

Supernovae are types of energetic explosions where the core of massive stars explode, liberating huge amounts of energy.
These events are visible through very far away distances much beyond our own solar system.
Super-luminous supernovae are a special type of explosions having energy output 10 or more times higher than that of standard supernovae.
