Dr. Paul S. Hardersen
Director, UND Space Studies Observatory
Dr. Paul S. Hardersen is a tenured associate professor at the University of North Dakota (UND) Department of Space Studies. Dr. Hardersen has been a faculty member of the department since August 2003 and earned his Ph.D. in geology from Rensselaer Polytechnic Institute (RPI) in May 2003. His doctoral dissertation work focused on the surface mineralogy and near-infrared reflectance spectral properties of M-type asteroids.
During his time as a faculty member in the department, Dr. Hardersen has continued the spectral studies of M-type asteroids. Additional spectral and mineralogical studies of S- and V-type asteroids have also been conducted. All of this research has utilized the NASA Infrared Telescope Facility (http://irtfweb.ifa.hawaii.edu ) on Mauna Kea, Hawaii. Support of the M-asteroid research has been received from the NASA Planetary Astronomy Program from 2005-2010.
Besides the asteroid studies, Dr. Hardersen has been collaborating with Dr. K.S. Balasubramaniam, U.S. Air Force Research Laboratory, Kirtland Air Force Base, New Mexico, on the analysis of ground-based imagery of the solar photosphere and chromosphere. The main goal of this pilot project on intrinsic sunspot rotations is to determine if such rotations can be detected and if any rotations are related to the occurrences of solar flares. The initial results of this work were published in The Astrophysical Journal in August 2013.
Current research projects include a continuation of the sunspot intrinsic rotation studies, initiation of a new study of solar filaments in collaboration with Sara Martin at Helio Research Inc., and a spectral and mineralogical study of V-type asteroids associated with (4) Vesta and those in the outer main-belt that are not associated with (4) Vesta.
