Astrophysics Sessions with Steve Shore

Agenda 2025-2026

• 2025 September 12th Young stellar objects
  Herbig Ae, T Tau, FU Ori (and FUOrs), Herbig-Haro objects
  
• 2025 October 10th 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)
  
• 2025 December Advanced stages of ordinary stellar evolution
  red giants and supergiants, AGB stars; Mira, RV Tau and semi-regular variables
• 2026 January: The Light as electromagnetic wave

Agenda 2024-2025

• 2024 September: Novae at multiwavelengths
• 2024 October: Accretion processes onto white dwarfs
• 2024 November; Planetary Nebulae

1. What we know about the universe beyond the heliosphere is entirely remote sensing and for understanding the majority of cosmic sources this requires measuring light. So far, in our discussions the emphasis has been on spectroscopy but there are other properties — photometry and polarization — that when combined with spectra provide vital information about environments and consituents. Even the fundamental tool of the business, the telescope, depends on a specific property of electromagnetic waves — phase — that explains the formation, and the distortion, of images, applying to everything from adaptive optics and corrections for turbulent media to interferometers to dispersion of pulsar signals by the interstellar medium to gravitational lensing. ↩︎
