IUE and IRAS observations of luminous M stars with varying gas-to dust ratios

, 1986
Circumstellar gas and dust surrounding M giants and supergiants show luminous M stars to split into two distinct classes. Stars with a high gas to dust ratio all show chromospheric Ca II, H, and K emission. Stars with a high dust to gas ratio do not show

The influence of grain growth in circumstellar dust envelopes on observed colors and polarization of some eruptive stars

, 1989
R CrB stars are classical examples of stars where dust envelope formation takes place. Dust envelope formation was detected around the Kuwano-Honda object (PU Vul) in 1980 to 1981 when the star's brightness fell to 8(sup m).

Infrared emission towards SN 1987A, 11 years after outburst: Properties of the circumstellar dust

, 2002
Detailed models are presented for the late epoch mid infrared (MIR) emission from collisionally heated grains in the shocked circumstellar gas around SN 1987A.
