dc.description.abstract | We present observations and analysis of 18 stripped-envelope supernovae observed during 2013-2018. This sample consists of five H/He-rich SNe, six H-poor/He-rich SNe, three narrow lined SNe Ic, and four broad lined SNe Ic. The peak luminosity and characteristic time-scales of the bolometric light curves are calculated, and the light curves modelled to derive <SUP>56</SUP>Ni and ejecta masses (M<SUB>Ni</SUB> and M<SUB>ej</SUB>). Additionally, the temperature evolution and spectral line velocity curves of each SN are examined. Analysis of the [O I] line in the nebular phase of eight SNe suggests their progenitors had initial masses <20 M<SUB>☉</SUB>. The bolometric light curve properties are examined in combination with those of other SE events from the literature. The resulting data set gives the M<SUB>ej</SUB> distribution for 80 SE-SNe, the largest such sample in the literature to date, and shows that SNe Ib have the lowest median M<SUB>ej</SUB>, followed by narrow-lined SNe Ic, H/He-rich SNe, broad-lined SNe Ic, and finally gamma-ray burst SNe. SNe Ic-6/7 show the largest spread of M<SUB>ej</SUB> ranging from ∼1.2-11 M<SUB>☉</SUB>, considerably greater than any other subtype. For all SE-SNe <M<SUB>ej</SUB>> = 2.8 ± 1.5 M<SUB>☉</SUB> which further strengthens the evidence that SE-SNe arise from low-mass progenitors which are typically <5 M<SUB>☉</SUB> at the time of explosion, again suggesting M<SUB>ZAMS</SUB> <25 M<SUB>☉</SUB>. The low <M<SUB>ej</SUB>> and lack of clear bimodality in the distribution implies <30 M<SUB>☉</SUB> progenitors and that envelope stripping via binary interaction is the dominant evolutionary pathway of these SNe. | en_US |
