Group Summary:

1
Group Summary

• Stars and Their Evolution
• ALMA Science Workshop

2
Science Summaries

• The stellar theme involves different kinds of
  science, from the Sun to active stars to stellar
  atmosphere studies to dying stars and dead stars
  will utilize the full complement of sensitivity,
  spatial spectral resolution, mosaicing
  capabilities of ALMA

3
Science not in DRSP

• Interacting winds e.g. MWC 349, recombination
  line maser with BIMA, relatively few sources, but
  very bright (20 Jy), so ALMA should see more of
  these
• Eta Carina radio outbursts
• ESP work -gt targets for TPF (tie in with NASA
  ?)
• Astrobiology (tie in with NASA ?)
• Astrometry/PM of embedded objects, star forming
  regions (not possible with SIM)

4
Issues 1

• Software - ??
• Image analysis tools general modelling tools
  for survey work (e.g. XPEC, CIAO for X-ray
  astronomy)
• Support for faculty postdocs, not just grad
  students
• CV site host workshops (focus on science area)
  for broader impact, talk series
• Support astronomers -gt independent research time
  (HST model of data analysts?)

5
Issues 2

• ALMA scientists to work with new mm/sub-mm users
• Big emphasis on EPO for public support and
  funding
• Multi-wavelength perspective crucial, how to
  coordinate with ground-based space-based
  observatories (policy?, time sharing?)
• Short time variability Sun essential, other
  projects also necessary (stellar flares)
• Keep VLBI possibility e.g. AGB stars

6
Frequency Bands

• Change nomenclature!!! Band 5 is meaningless to
  the astronomical community use center frequency
  or wavelength instead
• Band 1 impt SiO line, Ka band NASA spacecraft
  communication (?)
• Band 5 impt H2O line, evolved stars CS
  envelopes, thermal H2O emission in ISM
• Band 4 impt multitude of molecular lines in CS
  envelopes
• Band 8 C I HDO (or get H2O with Band 5)

7
ACA

• Roughly 50 of stellar theme DRSP requests
  ACA/mosaicing capabilities
• Sun absolute necessity of mosaicing
• Stellar envelopes need 1 arcminute scales
• Dirty secret of interferometry mosaicing to get
  uniform sensitivity

8
Early Science

• First light objects planetary nebulae, AGB
  stars -gt pretty images significant science
• Eta Car, SN 1987A, Beta Pic disk
