Steve Shore lectures 2025-2026

[Francois Teyssier]

Season 2 began in September with the Young Stellar Objects

2025 October Be stars
and the combined effects of rotation, decretion (disks), and outflows (winds), interpretation of spectra of composite systems; why this is different than cataclysmics; binary stars among the Be stars

2025 November Pulsation
mechanisms and observations (photometric and spectroscopic), including irregular variables; radial and nonradial oscillations; periodic oscillations and music (I hope you like this one)

2026 May: The absortion spectrum of a Nova
Around the time of maxium, when the ejecta are optically dense, the nova exhibits a complex absorption spectrum. Seminal studies Payne-Gaposchkin (1957), McLaughlin (1960) have described these phases as pre-maximum,principal, diffuse enhanced, Orion spectra whose velocity generally increase with time. The theme of the next session will be how the structure and evolution of the ejecta, and its opacity, help us to understand these variations in velocity and profile.

2026 July: Add metals, mix well, recycle the refuse: the chemical evolution of the Galaxyalactic compost heap: the drivers of Galactic chemical evolution
Stars are the factories of the elements and the dispersers of the products. We’ve examined the diagnostics of winds, novae, supernovae, mergers, planetary nebulae and AGB stars. How those combine to pollute the interstellar medium and accumulate in successive generations of stars is the connection between the Galaxy and life, the Universe, and everything. This session will treat the great bridge: how stars govern their own evolution.
