<b>Title: </b>Neutron stars and peculiar stripped-envelope supernovae
<br>
<br>
<b>Abstract: </b> <br>
Massive stars end their life when the iron core exceeds the Chandrasekhar mass limit and collapses.
<br>
In the majority of massive stars, a neutron star is born and the outer envelope gets ejected in a core-collapse supernova.
<br>
The neutron star often plays no role in the subsequent cosmic firework; but when it does, it can create an even more spectacular explosion.<br>
In this talk, I will discuss two extreme hydrogen-poor, stripped-envelope supernovae that have likely been powered by a central neutron star.
<br>
First, I will discuss SN 2020wnt, a very luminous supernova similar to the magnetar-powered superluminous supernovae.
<br>
But unlike a typical superluminous supernova, SN 2020wnt only shows weak signatures of the neutron star at late times.
<br>
It is the latest and most luminous member of a growing class of over luminous but spectroscopically normal stripped-envelope supernovae.
<br>
Second, I will discuss SN 2014C, a hydrogen-poor supernova that starts interacting strongly with its progenitor’s lost hydrogen-rich envelope.
<br>
Remarkably, very late time spectra reveal that a different powering mechanism, perhaps from the central neutron star, may be at play.
<br>
I will discuss how upcoming instruments and surveys will help us quantify the roles neutron stars play in core-collapse supernovae.<br>
