Call for Follow-Up Observations of the Dynamically Changing Triple Star KIC 2835289

TL;DR

This paper calls for community follow-up observations of the triple star system KIC 2835289, which exhibits complex dynamical behavior and upcoming eclipse events, to improve photodynamical models.

Contribution

It highlights the need for additional ground-based observations of KIC 2835289's upcoming eclipse to better understand its dynamical properties.

Findings

Two eclipse events observed by Kepler so far.

Upcoming eclipse on May 14 UT will provide crucial data.

Community involvement is essential for follow-up observations.

Abstract

KIC 2835289 is a triple stellar system that consists of an inner ellipsoidal variable with an orbital period of ~0.86 days and an outer star that eclipses the inner pair every ~750 days. Two eclipse events were observed by the Kepler mission, but they do not fully constrain our photodynamical models. The next eclipse event will occur on May 14 UT, and we solicit community involvement to follow it up from the ground. All details are available in the attached call. Please contact the authors to join the follow-up campaign.
