Stellar Notes
SRd 5.34 - 5.54V, 68:d.
IR excess.
2- and 10-micrometer spectra show silicate emission indicating circumstellar shell. Infrared emission at wavelengths | longer than 2 micrometers probably originates in circumstellar shell of solid particles.
About 70d. Mass loss 10E-08 solar masses/y.
