A Canadian-led international team of astronomers recently discovered for the first time observational evidence explaining how features at the surface of the hot massive supergiant star Zeta Puppis induce the formation of fundamental structures in its wind.
The research team used the network of nanosatellites of the BRIght Target Explorer (BRITE) space mission - of which RMC Physics and Space Science Department Head Gregg Wade is the Canadian PI - to monitor the visible brightness changes coming from the surface of Zeta Puppis over about six months, and simultaneously monitored the behavior of the wind of the star from several ground-based professional and amateur observatories.

Dr. Sabat from the Department of Physics and Space Science at RMC, along with Dr. Escobedo and his PhD student Srijit Nair from Queen’s university, developed a light-based bio-molecular sensor for protein binding detection in fluids, via measuring a very small refractive index change of the fluid. This biosensor will prove very useful in biomedical applications because it allows the detection of very small concentrations of toxins or other biological molecules in liquids. Further details, with a link to the published article.
RMC research assistant (and Queen’s PhD candidate) Zsolt Keszthelyi, in collaboration with RMC Professor of Physics and Space Science Gregg Wade and an international team of collaborators, propose a novel mechanism - strong magnetic fields at the surfaces of hot stars - leading to the formation of “heavy” stellar-mass black holes as detected by the LIGO (Laser Interferometer Gravitational-Wave Observatory) collaboration in the source GW150914. Their results were recently featured in the popular press.
