The Evolution of Luminous Red Nova AT 2017jfs in NGC 4470
A. Pastorello, T. -W. Chen, Y. -Z. Cai +43
We present the results of our photometric and spectroscopic follow-up of the intermediate-luminosity optical transient AT 2017jfs. At peak, the object reaches an absolute magnitude…
A luminous stellar outburst during a long-lasting eruptive phase first, and then SN IIn 2018cnf
A. Pastorello, A. Reguitti, A. Morales-Garoffolo +45
We present the results of the monitoring campaign of the Type IIn supernova (SN) 2018cnf (aka ASASSN-18mr). It was discovered about 10 days before the maximum light (on MJD = 58293…
Beryllium detection in the very fast nova ASASSN-16kt (V407 Lupi)
L. Izzo, P. Molaro, P. Bonifacio +8
We present high-resolution spectroscopic observations of the fast nova ASASSN-16kt (V407 Lup). A close inspection of spectra obtained at early stages has revealed the presence of l…
A new method for estimating the bolometric properties of Ibc SNe
Zach Cano
The bolometric properties (nickel mass, ejecta mass and kinetic energies) of 61 Ibc supernovae (SNe), including 20 Gamma-Ray Burst and X-Ray Flash (GRB/XRF), 19 Ib, 13 Ic and 9 Ic-…
XRF 100316D / SN 2010bh and the Nature of Gamma Ray Burst Supernovae
Z. Cano, D. Bersier, C. Guidorzi +21
We present ground-based and HST optical and infrared observations of XRF 100316D / SN 2010bh. It is seen that the optical light curves of SN 2010bh evolve at a faster rate than the…
Does the RR Lyrae variable DY And show the Blazhko effect?
Zachariah Cano, Robert Connon Smith
Data taken on the University of Sussex 0.46-m telescope in 2006 and 2007 are combined with previously published data to obtain a better defined light curve for the RRab-type variab…
