EROS light-curve database

Astronomy & Astrophysics
Context. The project called Expérience de Recherche d’Objets Sombres (EROS) carried out photometric surveys of dense stellar fields toward the Magellanic Clouds (LMC and SMC), the Galactic bulge and Galactic spiral arms in the period 1990-2003.

Diversity of Kilonova Light Curves [PDF]

The Astrophysical Journal, 2020
Abstract We perform radiative transfer simulations for kilonova in various situations, including the cases of prompt collapse to a black hole from neutron star mergers, high-velocity ejecta possibly accelerated by magnetars, and a black hole–neutron star merger.

Focusing light in a curved-space

Optics Express, 2010
We use transformation optics to demonstrate 2D silicon nanolenses, with wavelength-independent focal point. The lenses are designed and fabricated with dimensions ranging from 5.0 microm x 5.0 microm to 20 microm x 20 microm. According to numerical simulations the lenses are expected to focus light over a broad wavelength range, from 1.30 mum to 1.60 ...

On the Quality of Deep Representations for Kepler Light Curves Using Variational Auto-Encoders

Signals, 2021
Light curve analysis usually involves extracting manually designed features associated with physical parameters and visual inspection. The large amount of data collected nowadays in astronomy by different surveys represents a major challenge of ...

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 ...

A Photometric Study of Near-Contact Binary ZZ Aur [PDF]

Journal of Astronomy and Space Sciences, 2002
The BVR CCD full light curves of ZZ Aur were obtained as one of the near-contact binary observing programs at the Sobaek Mt. Observatory during Feb. 2000 - Feb. 2001. From the present observations, three primary and seven secondary times of minimum light
