Research

Dr. Wade investigates the structure, evolution, origin and impact of magnetic fields in stars. His research concentrates on intermediate and high mass stars, which are the evolutionary progenitors of most white dwarfs, neutron stars and stellar-mass black holes. His current research aims at understanding the origin of and evolution of magnetic fields in stars; the role of magnetic fields in generating spectroscopic activity and in mediating accretion in late stellar formative stages; the interaction of magnetic fields and stellar winds; the factors influencing stellar rotational angular momentum; and the ultimate impact of internal and external magnetic fields on stellar evolution.

Dr. Wade is the Principal Investigator (PI) of the Magnetism in Massive Stars (MiMeS) collaboration, co-PI of the Binarity and Magnetic Interactions in Stars (BinaMIcS) project, and past-Chair of the international BRITE Executive Science Team (BEST) for the BRITE-Constellation mission.

In the context of RMC’s Space Surveillance Research Laboratory (SSRL), Dr. Wade has also directed research related to the characterization of the structure, surface composition, and rotation of artificial satellites.

Dr. Wade was awarded RMC’s Cowan Prize for Excellence in Research in 2019.

Now hiring: summer undergraduate research assistants

Dr. Wade is currently recruiting undergraduate research assistants to join his research team from May through August 2021 to contribute to projects in the field of stellar magnetism and evolution. Successful applicants will have successfully completed at least one year of a Bachelor’s degree in Astrophysics or Physics, and qualify for NSERC’s Undergraduate Student Research Award program.

Applications should consist of a cover letter motivating the application, a complete CV, and the names and contact details of two referees (at least one of whom should be a professor or other individual capable of commenting on the applicant’s academic ability and research potential). All applications should be sent in electronic format to gwade@queensu.ca. The deadline for receipt of applications is 26 February, 2021.
