Catalog of 93 Nova Light Curves: Classification and Properties [PDF]

, 2010
We present a catalog of 93 very-well-observed nova light curves. The light curves were constructed from 229,796 individual measured magnitudes, with the median coverage extending to 8.0 mag below peak and 26% of the light curves following the eruption ...

BVRIJK light curves and radial velocity curves for selected Magellanic Cloud Cepheids [PDF]

, 2004
We present high precision and well sampled BVRIJK light curves and radial velocity curves for a sample of five Cepheids in the SMC. In addition we present radial velocity curves for three Cepheids in the LMC.

A New Statistical Approach to the Optical Spectral Variability in Blazars

Galaxies, 2016
We present a spectral variability study of a sample of about 25 bright blazars, based on optical spectroscopy. Observations cover the period from the end of 2008 to mid 2015, with an approximately monthly cadence.

Interpretation of Strong Short-Term Central Perturbations in the Light Curves of Moderate-Magnification Microlensing Events [PDF]

, 2009
To improve the planet detection efficiency, current planetary microlensing experiments are focused on high-magnification events searching for planetary signals near the peak of lensing light curves.

Predicting Variable Star Light Curves [PDF]

International Astronomical Union Colloquium, 1993
AbstractI present a new method to test determinism, in particular the nonlinear behavior, in observed time series of pulsating stars, based on a recent prediction method which exploits the dynamical system theory. A method for filling gaps in data has thereby been constructed.

Scintillation Caustics in Planetary Occultation Light Curves [PDF]

, 2003
We revisit the GSC5249-01240 light curve obtained during its occultation by Saturn's North polar region. In addition to refractive scintillations, the power spectrum of intensity fluctuations shows an enhancement of power between refractive and ...

RobPer: An R Package to Calculate Periodograms for Light Curves Based on Robust Regression

Journal of Statistical Software, 2016
An important task in astroparticle physics is the detection of periodicities in irregularly sampled time series, called light curves. The classic Fourier periodogram cannot deal with irregular sampling and with the measurement accuracies that are ...

Bolometric and UV Light Curves of Core-Collapse Supernovae [PDF]

, 2013
The Swift UV-Optical Telescope (UVOT) has been observing Core-Collapse Supernovae (CCSNe) of all subtypes in the UV and optical since 2005. We present here 50 CCSNe observed with the Swift UVOT, analyzing their UV properties and behavior.
