most core-collapse supernovae are influenced at some level by
interaction with circumstellar material. Although considered so far a
feature in core-collapse supernovae, this observation has led
theorists to revise the idealized view of massive star evolution and
explosion, introducing a slew of time-dependent, dynamical, and
multi-dimensional effects that remain today poorly understood.
In this talk, I will review the basic features of massive star evolution,
the ultimate gravitational collapse of their degenerate core, and their
explosion as supernovae. I will then describe the variety of signatures
that are suggestive of ejecta interaction with circumstellar material,
how we model the radiation and the dynamics of these events, and how
these new results reshape our understanding of massive star evolution
and explosion.
