Study of CoRoT 105415473: A Heartbeat Star with δ Scuti Oscillations

Chou, Dean-Yi; Fernández Fernández, Javier

We study the light curves of CoRoT 105415473 with the CoRoT satellite photometric data of 144 days. The light curves consist of two types of temporal variations: periodic brightening and pulsational. The periodic brightening suggests that the variations are from a binary system without eclipsing, with an orbital period of 2.6 days. The frequency a…

A Method to Identify and Characterize Binary Candidates—A Study of CoRoT Data

Da Silva, Ronaldo; Silva-Valio, Adriana

The analysis of the CoRoT space mission data was performed aiming to test a method that selects, among the several light curves observed, the transiting systems that likely host a low-mass star orbiting the main target. The method identifies stellar companions by fitting a model to the observed transits. Applying this model, which uses equations s…

Jitter Correction Algorithms for the COROT Satellite Mission: Validation with Test Bench Data and MOST On-Orbit Photometry

Auvergne, M.; Drummond, R.; Aerts, C. +5 more

We demonstrate the effectiveness and robustness of photometric correction algorithms for satellite pointing jitter in the upcoming space mission COROT, which will study asteroseismology and search for exoplanets. Two algorithms based on model-based estimation and decorrelation are tested in two ways: (1) with artificial light sources in the COROT …
