Montana State University

Heliophysics Journal Club

In this seminar, graduate student and faculty participants will review recent journal articles and preprints in order to familiarize themselves with the "state of the art" of the major observational and theoretical research topics of the discipline and the MSU research program. From time to time, "classic" papers of enduring value may be discussed. The typical weekly meeting will consist of a one-hour critical discussion of a journal article, copies of which will have been distributed to, and read by, all participants during the previous week. Each discussion will be informally led by a student or faculty member. Participants will be expected to contribute actively to all discussions, and to lead an occasional one on a rotating basis. When appropriate, these discussions will be replaced by an informal presentation of personal research results by MSU students, faculty, or scientific visitors.
