Hi,

This talk (Dunsink, Monday 18th at 8pm) should be very interesting.

Planetary Nebulae hold many attractions:
1. Many have a fairly high surface brightness making them ideal tragets from towns & cities for the amateur.

2. A few low surface brightness objects (such as the Helix Nebula) are even visible in binoculars in a rural site.

3. They are among the most photogenic targets in the sky. Just look at the HST photos (even without over processing).

4. They have a lot to tell about stellar evolution. They and their parent stars are the remnants of a solar-mass type stars at the end of their lives. It is still not known exactly the mechanism of formation. Our own sun is predicted to reach that stage in 5 billion years or so.

This should be a really interesting talk. All are welcome and admission is free. Make the effort to turn up it's worth it.

Apology - We appear to have a typo in the above poster. The name should read Mohsen, and not Moshen.

I've been googling Dr. Shadmehri and have readily encountered many interesting papers to do with Molecular Cloud collapse etc. If your coming to the talk this evening and have a bit of time to kill do a google on his name and scan through some of the papers he has been involved with e.g. www.astrosmo.unam.mx/~g.gomez/publica/be.pdf . It might help to prompt a question or two.
