- W2000720215 abstract "In an attempt to add to the information known about Ρ Cygni-like stars, photometric and spectroscopic observations have been made of two little-known southern-hemisphere variable stars. The variability of the star AG Carinae (CoD -59° 3430 = CPD -59° 2860 = HD 94910 = GC 15044; « = 10h52*2, δ = -59° 55'; 1900) was discovered by Wood (1914). Mrs. Greenstein (1938) published a photographic light curve which showed that AG Car varied slowly and irregularly over a range of nearly two magnitudes. The star presents a remarkable system of a Ρ Cygni star surrounded by a low-excitation, ring-shaped shell, first discovered by Thackeray (1950). Direct photographs of this nebula have been published by Thackeray (1956) and also by Westerlund and Henize (1967). The light curve has been updated recently by Mrs. Mayall (1969). Hertzsprung (Hoffleit 1940) discovered the variability of HR Carinae (CoD -59° 3044 = CPD -58° 2145 = HD 90177 = GC 14276; a = 10h19^4, δ = -59°07'; 1900). The photographic light curve compiled by Miss Hoffleit (1940) showed HR Car to vary slowly by perhaps 1TM5 in an irregular fashion." @default.
