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

open access: yesSignals, 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 ...

The All-Sky Automated Survey for Supernovae (ASAS-SN) Light Curve Server v1.0 [PDF]

open access: yes, 2017
The All-Sky Automated Survey for Supernovae (ASAS-SN) is working toward imaging the entire visible sky every night to a depth of V ∼ 17 mag. The present data covers the sky and spans ∼2–5 years with ∼100–400 epochs of observation. The data should contain

Modelling the light curve of ‘Oumuamua: evidence for torque and disc-like shape [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2019
We present the first attempt to fit the light curve of the interstellar visitor ‘Oumuamua using a physical model that includes optional torque. We consider both conventional (Lommel–Seeliger triaxial ellipsoid) and alternative (‘black-and-white ball’, ‘

A Meteor Detection Algorithm for GWAC System

open access: yesUniverse, 2023
Compared with the international meteor surveillance systems, the ground wide angle camera (GWAC) system exhibits characteristics such as images with the resolution of 4K × 4K and single-site observation.

Radioactive Heating Rate of r-process Elements and Macronova Light Curve [PDF]

open access: yesAstrophysical Journal, 2019
We study the heating rate of r-process nuclei and thermalization of decay products in neutron star merger ejecta and macronova (kilonova) light curves.

Asymmetric Light Curves of Black Hole Binaries and the Doppler Beaming Effect [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2002
Black hole binary candidates are known to be composed of a black hole with 10Msolar and a K or M type companion. Because the companion is believed to fill the Roche lobe that is very aspherical, the light curves of black hole binaries are characterized ...

starry: Analytic Occultation Light Curves [PDF]

open access: yesThe Astronomical Journal, 2019
Abstract We derive analytic, closed form, numerically stable solutions for the total flux received from a spherical planet, moon, or star during an occultation if the specific intensity map of the body is expressed as a sum of spherical harmonics.

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

open access: yesJournal 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

Type IIn supernova light-curve properties measured from an untargeted survey sample [PDF]

open access: yesAstronomy & Astrophysics, 2019
The evolution of a Type IIn supernova (SN IIn) is governed by the interaction between the SN ejecta and a hydrogen-rich circumstellar medium. The SNe IIn thus allow us to probe the late-time mass-loss history of their progenitor stars.
