Research

The bulk of the research carried out at the Peter van de Kamp Observatory during its first few years has been focused on exoplanet transits, in which stars are dimmed by planets passing in front of them. We are participants in two exoplanet collaborations: KELT and YETI which are searching for exoplanets around host stars that are bright and young, respectively. Other projects involve studies of stellar rotation, optical signatures of accretion in young stars, and the winds of massive stars. Students are usually involved in these research projects.

Professors Jensen and Cohen both have active research programs beyond those related to the Peter van de Kamp Observatory, including current projects that involve the acquisition and analysis of data from the ALMA millimeter array in Chile and the Chandra X-ray Observatory.

Below is a list of publications that include data taken at the Peter van de Kamp Observatory.

Prof. Jensen has written the publicly-available software TAPIR: A Web Interface for Planning Astronomical Observations (ADS), which we, and many others, find very useful for seeing what transits are observable on a given night, making arimass plots for targets, and quite a few other things.
