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 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 also directs research related to the characterization of the structure, surface composition, and rotation of artificial satellites.

Summer students wanted

Dr. Wade is currently seeking summer undergraduate assistants to assist with research related to stellar evolution, variability, and magnetism for the period May-August 2019 (16 weeks). Selection will be based on academic achievement and prior research experience. Top candidates will be recommended for prestigious NSERC USRA awards. Stipends are competitive. Place of work is the RMC campus.

Interested candidates should apply directly to Dr. Gregg Wade with a statement of interest, CV, and postsecondary transcripts (unofficial marks records from e.g. a university website are acceptable). 

Deadline for applications is 8 February 2019.

Graduate students wanted

Dr Wade is seeking new graduate students to join his research team is September 2019. Exceptional students will be considered to start in May 2019. Potential projects include:

  • Characterizing the low-mass stellar hosts of terrestrial exoplanet candidates: We are witnessing the dawn of a new generation of infrared velocimeters that will detect and characterize Earth-like planets in the Habitable Zones of nearby M-dwarf stars. The aim of this project is to exploit observations acquired using the new SPIRou and NIRPS planet-hunting spectrographs to characterize the physical and magnetic properties of cool stars identified as hosts to terrestrial exoplanets. 
  • Identifying and characterizing the population of massive magnetic stars in the Magellanic Clouds: The Magnetism in Massive Stars (MiMeS) and Binarity and Magnetic Interactions in Stars (BinaMIcS) surveys have led to a firm understanding of the basic magnetic properties of hot, massive stars in the Milky Way. The next step is to understand how these properties depend on the properties of the host galaxy, in particular the galaxy’s metallicity. This project aims to exploit new and existing photometry and spectroscopy to identify magnetic candidate massive stars in the Magellanic Clouds, to study their physical and magnetospheric properties, and to obtained spectropolarimetric observations in order to obtain the first direct measurements of extra-Galactic stellar magnetic fields. 
  • Magnetic properties of massive protostars to understand the origins of fossil magnetic fields: Building on past and ongoing experience studying the magnetic fields of intermediate-mass and high-mass pre-main sequence stars, we will identify a population of embedded massive protostars suitable for observation with the SPIRou infrared spectropolarimeter. This will form the basis of an observational survey to detect their magnetic fields. Ultimately, we will monitor and model detected targets to determine their field characteristics as a first step toward understanding the relationships to those of their main sequence descendants. 

Applicants must have a BSc or MSc in Astronomy or a related field. Interested individuals should contact Dr. Wade directly.
