Harvard Astronomy 201b

Journal Club 2011

This page links to the journal articles discussed by the class in Spring 2011. Articles were selected from the AY201b Library at ADS. (For more choices… try the new ADS Labs!)

<!–

This page is a continual work in progress… alternative articles on the same topics as those shown here may be suggested by students.  Article selection will be finalized by a week before any article is to be read–and the AY201b Google Calendar here will then give the correct choice.
