Stellar Gas Clouds in the Galaxy: Insights from Molecular and Atomic Gas Studies

This study explores atomic and molecular gas in the galaxy, including observations of M33, M51, and Pipe Nebula, with an emphasis on extinction and evolutionary tracks of stars. Data from various tracers like CO emission and infrared imaging provide insights into stellar formation and evolution processes.

Presentation Transcript

  1. Atomic gas Molecular clouds Atomic and molecular gas in the galaxy M33 (Engargiola et al. 2003)

  2. M51 in CO emission (left) and optical (right) (Koda et al., 2009)

  3. Pipe Nebula (Lombardi, Alves, & Lada 2006) -- optical Pipe Nebula (Lombardi, Alves, & Lada 2006) -- extinction

  4. The Perseus molecular cloud in 13CO J=2-1, integrated over velocity (Sun et al. 2006)

  5. Infrared image of the W5 region from Spitzer

  6. The core B68 in a wide variety of tracers.

  7. Evolutionary tracks in the HR diagram for stars from 0.6 - 6 M. Only lower mass stars have a Hayashi track.
