EccentriCAT - LITE Project

Timing bright eccentric binaries with small and smart telescopes to study apsidal motion and orbital variations. A citizen science project.

In cooperation with Marek Wolf, Associate Professor at Charles University in Prague, we aim to monitor eccentric binary stars to detect and characterize apsidal motion and other phenomena revealed by times of minima. We are calling for citizen scientist with smart telescopes such as Seestar or another small diameters instruments.

The team

    Primary Investigator: Marek Wolf (Charles University Prague, Czechia) MarekWolf@seznam.cz
    Administrators: Filip Walter (CAS Variable Star Section, Stefanik Observatory Prague) walter@planetum.cz
    Local conatacts: Ivo Peretto, ITALY - Marana space explorer center, ricerca@marsec.it

Project focus:

Study of eccentric eclipsing binaries provides new information about the structure and evolution of stars. Analysis of the apsidal motion (i.e., the rotation of the line of apsides) yields the so‑called internal structure constant, an important parameter in all current stellar models. Apsidal motion also has a relativistic component, which therefore allows tests of the laws of general relativity outside the Solar System. In eccentric binaries we quite often find a third component whose influence on the eclipses can be separated in the O–C diagram.

The aim of the observations is to monitor the eclipses of known eccentric binaries and, by combining data over a longer time span, to derive or refine the period of the apsidal motion.

Data added to the project will be evaluated annually and analyses of selected systems will be published in a professional journal. Observers will be able to become co‑authors of the publications.

  • Selected targets: A growing list of known eccentric binaries of magnitudes up to 12 mag.
  • Method: Time of minima derived from primary and secondary eclipse observations.

How to participate:

    The photometry shall be taken in accordance with each target's instructions and priority described in the targets list below. For the purpose of this project a good coverage of eclipse is required - an observation shall have both descending and ascending branch of the eclipse clearly visible. Photometry shall be uploaded via VarAstro website and marked as part of the project. Please report GJD_UTC time standard with timestamp centered within the exposure interval. Use VarAstro built-in fitting tool to derive minima timings - the timing error shall not exceed 0.001 days. The data will be assessed for the compliance and feedback will be given to the observers by the coordination team. You are encouraged to upload any variable star photometry acquired during the project sessions.
