The radial pulsation of AI Aurigae [PDF]
, 2001 We present an analysis of eleven years of Stromgren by photometry of the red semiregular variable star AI Aurigae. An early period determination of 63.9 days is confirmed by the long-term light curve behaviour.

The shapes of light curves of Mira-type variables
, 2010 Using a sample of 454 mira light curves from the ASAS survey we study the shape of the light variations in this kind of variable stars. Opposite to earlier studies, we choose a general approach to identify any deviation from a sinusoidal light change. We

Machine Learning Techniques for Stellar Light Curve Classification [PDF]
, 2018 We apply machine learning techniques in an attempt to predict and classify stellar properties from noisy and sparse time series data. We preprocessed over 94 GB of Kepler light curves from MAST to classify according to ten distinct physical properties ...

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.

Mid-Infrared Variability of protostars in IC 1396A [PDF]
, 2009 We have used Spitzer/IRAC to conduct a photometric monitoring program of the IC1396A dark globule in order to study the mid-IR (3.6 - 8 micron) variability of the heavily embedded Young Stellar Objects (YSOs) present in that area.

Modelling of meteors light-curves [PDF]
Astronomical School’s Report, 2004 The computer model of a meteoric phenomenon is elaborated, which allows one to calculate standard light curve of a meteor using input parameters such as velocity, angle of an entry, mass and density of a particle.

PERFORMANCE - LIGHT SATURATION CURVE FOR GRAPEVINE PHOTOSYNTHESIS [PDF]
Scientific Papers Series : Management, Economic Engineering in Agriculture and Rural Development, 2021 Performance - Light saturation curve for photosynthesis is determined by the genetics of grapevine genotypes, through the physiological element - the degree of penetration of leaves by solar radiation, photosynthesis intensity, leaf structure ...

Light speed variation from gamma ray bursts: criteria for low energy photons
, 2018 We examine a method to detect the light speed variation from gamma ray burst data observed by the Fermi Gamma-ray Space Telescope (FGST). We suggest new criteria to determine the characteristic time for low energy photons by the energy curve and the ...

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.

Phase light curves for extrasolar Jupiters and Saturns [PDF]
, 2004 We predict how a remote observer would see the brightness variations of giant planets similar to Jupiter and Saturn as they orbit their central stars. We model the geometry of Jupiter, Saturn and Saturn's rings for varying orbital and viewing parameters.
