The Light Curve of S Andromedae [PDF]

, 2002
Historical observations of S And, in combination with the color versus rate-of-decline relationship for well-observed SN 1991bg-like supernovae, are used to estimate a rate of decline Delta m15 (B) = 2.21 and an intrinsic color at maximum [B(0) - V(0)]o =

PELICAN: deeP architecturE for the LIght Curve ANalysis [PDF]

Astronomy & Astrophysics, 2019
We developed a deeP architecturE for the LIght Curve ANalysis (PELICAN) for the characterization and the classification of supernovae light curves. It takes light curves as input, without any additional features.

Classical Machine Learning Techniques in the Search of Extrasolar Planets

CLEI Electronic Journal, 2019
The field of astronomical data analysis has experienced an important paradigm shift in the recent years. The automation of certain analysis procedures is no longer a desirable feature for reducing the human effort, but a must have asset for coping with ...

An investigation of 56Ni shells as the source of early light curve bumps in type Ia supernovae

Astronomy & Astrophysics, 2020
An excess of flux (i.e. a bump) in the early light curves of type Ia supernovae has been observed in a handful of cases. Multiple scenarios have been proposed to explain this excess flux.

Terrestrial Exoplanet Light Curves [PDF]

Proceedings of the International Astronomical Union, 2005
The phase or orbital light curves of extrasolar terrestrial planets in reflected or emitted light will contain information about their atmospheres and surfaces complementary to data obtained by other techniques such as spectrosopy. We show calculated light curves at optical and thermal infrared wavelengths for a variety of Earth-like and Earth-unlike ...

The bright optical/NIR afterglow of the faint GRB 080710 - Evidence for a jet viewed off axis [PDF]

, 2009
We investigate the optical/near-infrared light curve of the afterglow of GRB 080710 in the context of rising afterglows. Optical and near-infrared photometry was performed using the seven channel imager GROND and the Tautenburg Schmidt telescope.

K2 Observations of SN 2018oh Reveal a Two-component Rising Light Curve for a Type Ia Supernova [PDF]

Astrophysical Journal, 2018
We present an exquisite 30 minute cadence Kepler (K2) light curve of the Type Ia supernova (SN Ia) 2018oh (ASASSN-18bt), starting weeks before explosion, covering the moment of explosion and the subsequent rise, and continuing past peak brightness. These

An Algorithmic Approach for Detecting Bolides with the Geostationary Lightning Mapper

Sensors, 2019
The Geostationary Lightning Mapper (GLM) instrument onboard the GOES 16 and 17 satellites can be used to detect bolides in the atmosphere. This capacity is unique because GLM provides semi-global, continuous coverage and releases its measurements ...

The Orbital Light Curve of Aquila X-1 [PDF]

, 2000
We obtained R- and I-band CCD photometry of the soft X-ray transient/neutron- star binary Aql X-1 in 1998 June while it was at quiescence. We find that its light curve is dominated by ellipsoidal variations, although the ellipsoidal variations are ...
