Supernova models and light curves [PDF]

AIP Conference Proceedings, 1980
This talk briefly reviews the current status of our understanding of Type II supernovae with particular emphasis on the processes responsible for the emission of electromagnetic radiation. In addition, a relatively novel evolutionary scenario that appears to lead to a Type I supernova explosion is presented.

Light-curve and spectral properties of ultrastripped core-collapse supernovae leading to binary neutron stars [PDF]

, 2016
We investigate light-curve and spectral properties of ultra-stripped core-collapse supernovae. Ultra-stripped supernovae are the explosions of heavily stripped massive stars which lost their envelopes via binary interactions with a compact companion star.

Constraints on the Progenitor of SN 2016gkg from Its Shock-cooling Light Curve [PDF]

, 2016
SN 2016gkg is a nearby SN IIb discovered shortly after explosion. Like several other Type IIb events with early-time data, SN 2016gkg displays a double-peaked light curve, with the first peak associated with the cooling of a low-mass extended progenitor ...

The Transit and Light Curve Modeller [PDF]

Monthly Notices of the Royal Astronomical Society, 2020
ABSTRACT Transit and Light Curve Modeller (TLCM), a computer code with the purpose of analysing photometric time series of transits simultaneously with the out-of-transit light variations and radial velocity curves of transiting/eclipsing binary systems, is presented here.

Time Series Prediction and Anomaly Detection of Light Curve Using LSTM Neural Network

Journal of Physics: Conference Series, 2018
Ground-based Wide-angle Camera array (GWAC) is a short-time survey telescope which can produce images every 15 seconds for more than 30,000 stars. Light curve is generated from star image with a series of processing. Research on light curve is a new task

DETECTION OF POSSIBLE QUASI-PERIODIC OSCILLATIONS IN THE LONG-TERM OPTICAL LIGHT CURVE OF THE BL LAC OBJECT OJ 287 [PDF]

, 2016
The detection of periodicity in the broadband non-thermal emission of blazars has so far been proven to be elusive. However, there are a number of scenarios that could lead to quasi-periodic variations in blazar light curves.

The detailed optical light curve of GRB 030329 [PDF]

, 2004
(Abridged) We present densely sampled BVRI light curves of the optical transient associated with the gamma-ray burst GRB 030329, the result of a coordinated observing campaign conducted at five observatories. Augmented with published observations of this

Combining transient dynamics and logistic‐asymptotic growth to study the recovery of two seabird populations after rat eradication

Population Ecology, EarlyView.
This study examines the demographic dynamics of two seabird populations on Tromelin Island, 15 years after the eradication of brown rats. The results indicate that these populations are in good health and are expected to continue growing until breeding sites are saturated in about a century.
