... A spectrum of the HPMS taken on 11 July, 2002 using the Apache Point 3.5 m ARC telescope is shown Figure 2. ... For example, we derive M J = 11:58 0:35 for the HPMS, as compared with M J = 10:40 0:03 for GJ 1111. ...
... to the KMH model, with нЕ = 3.5, amin = 0.01 нјm and a0 = 1.0 нјm. The best-fit model produces an optical depth of 0.28 for the dust shell at the peak of the SiC feature (11.3 нјm), with an inner radius of about 1430 R_БЉ™ or 4.4 times the stellar radius ...
