Physical parameters of the continuum emission layer of Mira-type stars. I. Spectrophotometric temperatures

The spectrophotometric temperatures of five Mira-type variable stars are determined using observations in the Pulkovo spectrophotometric data base in the range from 320–1080 nm. All the resulting temperatures are below the effective temperatures of stars in the corresponding subclasses. Near the brightness maximum, the temperatures are found to be lower with increasing separation in time from the maximum. __________ Translated from Astrofizika, Vol. 50, No. 3, pp. 415–426 (August 2007).     

Physical parameters of the continuum radiating layer of the star L2 Pup

Data from spectrophotometric observations in the 485-1105 nm range at different times are used to determine the basic physical parameters of the continuum radiating layer of L₂ Pup: spectrophotometric temperatures, radii, and velocities of recession from the star's center. The phase dependences of these parameters over a cycle, during which the temperature varied from 2300 to 2900 K and the variations in radius were as high as 60%, are determined. The radius of the radiating layer is seen to vary irregularly, the radius of the layer is found to depend on wavelength, and the variations in the expansion velocity are evaluated.

Model atmosphere parameters of the binary systems COU1289 and COU1291

The spectral energy distributions between λ 3700 Å and λ 8100 Å of the binary systems COU1289 and COU1291 have been measured with the Carl‐Zeiss‐Jena 1 m telescope of the Special Astrophysical Observatory. Their B, V, R magnitudes and B – V colour indices were computed and compared with earlier investigations. Model atmospheres of both systems were constructed using a grid of Kurucz blanketed models, their spectral energy distributions in the continuous spectrum were computed and compared with the observational ones. The model atmosphere parameters for the components of COU1289 were derived as: T ^a_eff = 7100 K, T ^b_eff = 6300 K, log g _a = 4.22, log g _b = 4.22, R _a = 1.50 R_⊙, R _b = 1.40 R_⊙, and for the components of COU1291 as: T ^a_eff = 6400 K, T ^b_eff = 6100 K, log g _a = 4.20, log g _b = 4.35, R _a = 1.47 R_⊙, R _b = 1.12 R_⊙. The spectral types of both components of the system COU1289 were concluded as F1 and F7, and of the system COU1291 as F6 and F9. Finally the formation and evolution of the systems were discussed.

红外光谱差示因子定量法

作者从理论上证明差示因子f,代表两个同组分不同浓度的样品,在相同吸收谱带处光密度之比(浓度之比)为f=E_1(v)/E_2(v)=C_1/C_2。配制一个至一套(数个)标样即可进行差示因子法定量,差示因子由计算机处理图谱获得,因此,本方法快速、简便,省去了配制大量参比样的繁琐,也比工作曲线法方便。
