What happens at our meetings?

Doors open at 7:30 for the meeting due to start at 8:00 but several club members and friends gather before this to have a drink and chat in the bar.

Following welcome announcements we have a guest speaker who speaks on the subject of the evening for about 45 - 60 minutes.  This is followed by questions relating to the talk.

Announcements about forthcoming events follow.

You can then choose from the following activities:

  1. If the weather is clear telescopes and binoculars brought by members are set up outside for some observation.  Members doing so will be pleased to share their scopes with others.
  2. If you need help with some equipment then now is your chance to bring it in.  Others in our club will be more than willing to help you .  Don’t be shy, we get just as excited about a telescope bought at the charity shop for £20 as we do one costing many times more.
  3. Just socialise with others - about anything!

We look forward to seeing you.

Proto-Planetary Disks and Planet Formation

Cathie Clarke

In 1995 the first planet orbiting a star like our sun was discovered. Using a variety of methods the number of confirmed exoplanets is now around 3500. Planets come in very different masses and sizes and show interesting dynamics in their orbits.

Full planetary systems with up to 7 planets have been found as well as planets in binary stars systems, making science fiction a reality.

It has also become possible to study protoplanetary disks in unprecedented detail. These disks hold the reservoir of material from which planets may form, and they are considered to be the birthplaces of planets.
