The Life Cycle of a Star - from Gas Cloud to Black Hole

Dr.Colm Coughlan

by Dr. Colm Coughlan, DIAS

Monday March 30th 2015 (8 pm).
Venue: Ely House, 8 Ely Place, Dublin 2. Time: 8 pm. All welcome, free event.

This talk is about the life cycle of stars - from birth in stellar nebulae to the different ways in which they can end their lives. If time permits, he will also talk about how the stellar life cycle affects the evolution of galaxies.

Dr. Coughlan is originally from Newcestown in West Cork. He did an undergraduate degree in Applied Mathematics and Physics in UCC and stayed there to do a PhD on high resolution radio imaging of Active Galactic Nuclei under the supervision of Dr. Denise Gabuzda. He joined DIAS last September as a post-doctoral researcher in the star formation group in the school of cosmic physics. He is currently using the LOFAR radio array to study young stars (YSOs).

Partial Solar Eclipse from Ireland, 20 Mar 2015

partial eclipse

Despite a poor weather forecast and the day starting very grey and grim, many saw the eclipse through thin cloud or holes in the cloud.

The photo was taken by J. O'Neill, a little after maximum, through a hole in the clouds (85 mm refractor at 600 mm focal length).

The next partial solar eclipse visible from Ireland occurs in 2017, while for a total solar eclipse, the wait is for 2090!

Comet Lovejoy 2014 Q2 slow to fade

Comet Lovejoy C/2014 Q2 continues to be a nice object these evenings. The photo (below) of the comet is by John O'Neill and was taken on 9-10 January 2015 (cropped; 200 mm camera lens). The drawing of 19 January 2015 is by Deirdre Kelleghan, with details appended.

As March began the comet was about 6th magnitude. During the month the comet will fade a little, but still be an easy binocular object, as it moves in Cassiopeia. On the evening of 15th March it was very near (about 10') the bright star Delta Cassiopeiae. Did any members get any images?

Please report any observations, drawings or photographs to our Director of Observations, Liam Smyth.
