EB Working Group Charter. Eclipsing binary stars are the cornerstone of stellar astrophysics: This unique property, contrasted with other means of determining stellar radii that either apply to only a handful of objects such as resolving the disk of a star or are encumbered with a larger uncertainty i.
P—L—R relationships , promoted eclipsing binaries as calibrators of stellar properties. To perform such accurate modeling, we need to acquire both photometric and spectroscopic observations.
From Kepler photometry we can obtain the relative sizes of both components and their temperature ratio; for individual temperatures we require calibrated multi-band photometry, and for masses and an absolute scale of the system we require spectroscopy. Having these data available, modeling yields the fundamental parameters of the system components that are used to calibrate stars across the H-R diagram Harmanec , determine accurate distances Guinan et al.
The Kepler Eclipsing Binary working group is established to promote collaboration and communication within the binary star community interested in reducing, analyzing and modeling Kepler data. This includes acquiring follow-up observations, applying the methods from other fields i. To support the core Kepler mission, the Eclipsing Binary Working Group assumes the following tasks, in order of priority: Working Group members are expected to contribute to these core tasks.
Other Working Group Tasks Beyond these core goals, the members of the Working Group are involved in the supplementary goals. These are either individual projects or they can contribute to the core goals. This is conducted towards two primary goals: The supplementary goals are subject to change and refinement and follow individual interests. There is no limitation to adding any personal goals that are not listed above. The core task of cataloging EBs allows for cherry-picking targets with the most promising scientific yield.
Working Group Communication The main communication is done via the mailing list: Subscriptions should be done with a full name and an institutional email.
Confirmation is necessary and might take up to 3 days. Please note that all communication is archived and the archives are accessible to all working group members, present and future. All emails to the mailing list must be treated as confidential since sensitive information is discussed and disseminated on a regular basis. To keep the communication open and unhindered, never copy or forward emails to non-members. Please also refrain from posting any programmatic issues and concerns you may have; instead, those should be directed to the Steering Committee.
The telecons are open to all members. The dial-in information, weekly agenda and minutes are posted on the mailing list. Publication Policy The publications that arise from collaborative effort within the Working Group need to follow the basic policy: All co-authors must send in a statement that: Co-authorship based on merit to the mission i. Organizational Structure EB Working Group is built on open communication, open access and the free flow of data and information.
To promote the work towards achieving the main science goals of the working group, a formal structure of the Working Group is organized that consists of: The role of the Chair is to serve as a point of contact for the Working Group, to organize the telecons, set up relevant agenda and ensure that the main Working Group tasks are being met.
The Chair is elected every 2 years. The Steering Committee is tasked to overview the projects, goals, progress and effort towards achieving the core tasks. The Committee reviews membership applications and has authoritative power in case of disputes or violations of the rules of conduct. The Kepler Exoplanet Council provides scientific input to the Kepler project. The role of the Representative is to serve as the point of contact within the Kepler project: Any individual or a group from the broad scientific community may apply for membership in the EBWG.
The applications are reviewed by the Steering Committee. An application is an electronic letter that contains the following: Applications are reviewed and the applicants are typically notified within 1 week of application receipt. The list of members is public and can be accessed here.
To facilitate complete and timely sharing among WG members, members agree to protect all intellectual property shared at telecons, in meetings, via e-mail exchanges, etc. The intent is not to limit information exchange but to enable it. Information is to be taken in its broadest context; it includes data, results, figures, text, code, ideas, plans, goals, speculations, etc.
Members are encouraged to work on whatever project interests them, but they also have a responsibility to contribute to the EBWG's core goals and support the Kepler Extended Mission objectives. While volunteers are always solicited first, on occasion tasks may be delegated to members. Such tasks may be very minor e. When a member wishes to lead an investigation, it is their responsibility to make the scope of the project known to the EBWG before the project starts, and to post the information so that others in the EBWG can view it.
Others can then offer to contribute to the investigation at the start. Status reports of the investigation are expected. Others may join the investigation at any time, with the only constraint being that they contribute something significant to the project.
In general, there is no limitation on numbers of authors on EBWG papers. If a member decides that they no longer wish to lead an investigation, or that time constraints do no permit a timely completion of the paper, the investigation should be offered to others.
If two or more members wish to lead the same investigation, every effort will be made by the Steering Committee to fairly decide who will run the investigation and be lead author. Violation of the standards for professional behavior will result in dismissal from the EBWG.
