AstroMcGill Podcasts

On March 14, 2014, the Astro folks at McGill recorded and then produced a podcast about our research. It provides a laymen's introduction to the research we do. Check out Episode 47, Season 3, available as well on iTunesU (search AstroMcGill) or via this direct link.

Merging stars at CFAX radio

In conjunction with a public talk series at the University of Victoria in celebration of the new University Telescope Herwig is giving a radio interview with local radio station CFAX to talk about his presentation Violent Interactions of Merging Stars.

'Van Gogh' Simulations Give New Insight Into Turbulent Stars

Some coverage of our stellar hydrodynamics work at ScienceDaily.com.

Some Rare Abnormal Stars may have White Dwarf Parents to Blame

We found stars with the largest amount of 18O to 16O ever observed. The only way we can think of a way this nucleosynthetic signature could have been produced is through a double-degenerate merger involving a He- and a CO-white dwarf. There was a Gemini observatory press release that announces our new observations. The first such observation was reported in Clayton etal 2005, ApJ 623, L141. The new paper has been submitted (Jan 07) to ApJ.

Red Giant Plunging Through Space

Originally we wanted to find spherical variations in the circumstellar dust envelopes of cool dying giant stars, the Asymptotic Giant Branch stars. But then we found instead a bow shock around R Hydrae with the Spitzer Space Telescope.

A trip through a star

In the November 2006 issue of Sky \& Telescope, page 14, Robert Naeye reports about work by Pierre Maxted etal from Keele Universtiy and our theory and modeling team at LANL, lead by Steven Diehl, about a brown dwarf that was engulfed by a red giant and lived to tell the tale. The short article is entitled "A Trip Through a Star" and more details are available about the simulations as well from ESO and about the observations at Leicester.

Sakurai's object

The University of Manchester press release, picked up by Universe Today, and CNN.
