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.
