The same process apparently explains the bipolar "Homunculus Nebula" surrounding the enigmatic eruptive star Eta Carinae, one of the most luminous stars in the Milky Way at a distance of 7,500 light-years.
His variables also include R Leporis, known as Hind's Crimson Star (S&T: March 1994 issue, page 72), and the young eruptive star T Tauri, associated with Hind's Variable Nebula (see last month's issue, page 98).
He also explores variable stars such as Cepheids, red giants, and eruptive stars. He describes the formation of stars, their aging processes, and the composition of the interstellar medium, including clouds of dust that form nebulae.
This programme was set up as a joint project between the BAA VSS and The Astronomer magazine specifically to monitor poorly studied eruptive stars of various types where outbursts occur at intervals of greater than 1 year.
