The Continuing Slow Decline of AG Pegasi
The Continuing Slow Decline of AG Pegasi
We analyze optical and ultraviolet observations of the symbiotic binary AG Pegasi acquired during 1992–1997. The bolometric luminosity of the hot component declined by a factor of 2–3 from 1980–1985 to 1997. Since 1992, the effective temperature of the hot component may have declined by 10%–20%, but this decline is …
