Metamorphosis before entering the stellar graveyard

Open Night on 23 February 2019
“Metamorphosis before entering the stellar graveyard”

Overview

Members of the public are welcome to an Open Night at the SAAO in Cape Town on 23 February 2019, starting at 20h00. Dr. Brent Miszalski (SALT) will present a talk titled Metamorphosis before entering the stellar graveyard. This will be followed by a tour of the site and (weather permitting) star gazing.

Summary of the talk

Heavy stars end their lives with a bang as supernovae, enormous explosions that are seen to great cosmic distances. But did you know what happens to less massive stars like the Sun when they die? Before they enter the stellar graveyard, stars like the Sun can undergo a remarkable metamorphosis into cosmic butterflies producing wonderful nebulae. On top of that, if the star has a friend, such as a companion star orbiting around it, the shape of its cosmic butterfly can be especially peculiar.

In this talk, Dr. Miszalski will discuss some recent results from the Southern African Large Telescope (SALT) that give new insights into the final stages of stars like the Sun.

Venue

The Open Night will take place at the SAAO in Cape Town. The SAAO is located off Liesbeeck Parkway, next to the River Club.
