Binary light curves
WebFeb 28, 2024 · The shapes of the light curves allow us to assume a superposition of multiperiodic pulsational light variation on a typical eclipsing binary light curve (Fig. 1) as seen in many previous systems investigated in the literature (Kim et al. 2003). The duration of primary and secondary minima are about 11 and 9 hours for CPD-30 740, 9.5, and 12 ... WebJan 5, 2024 · There is a temptation to publish light curve analyses and to make assumptions to derive absolute parameters, with subsequently overconfident musings on things like the evolutionary history of the system. A particularly bad example is the analysis of the light curve of an overcontact binary with partial eclipses.

In astronomy, a light curve is a graph of the light intensity of a celestial object or region as a function of time, typically with the magnitude of light received on the y-axis and with time on the x-axis. The light is usually in a particular frequency interval or band. Light curves can be periodic, as in the case of eclipsing binaries, Cepheid varia…
WebLab 4 – Binary Stars ASTR 1020 Name: Overview In this activity, you will explore the behavior of two stars in a binary system and use the light curve of the system and the velocities of the two stars to derive physical stellar properties.
