Spectroscopy and orbit determination of the chromospherically active double-lined binary system HD 163621 = V835 Herculis

Autor: Francis C. Fekel, R. E. Fried, M. D. Morton, R. F. Griffin

Publikováno v: Journal of Astrophysics and Astronomy. 15:309-319

HD 163621 is a double-lined spectroscopic binary in a circular orbit whose period is 3.3 days. Spectral classification of the components has proved difficult, but current results of K0 V and late K V are reasonably consistent with our best model of t

Radial velocity measurements of the chromospherically-active stars (II)

Autor: Francis C. Fekel, V. Dadonas, M. D. Morton, Julius Sperauskas

Publikováno v: Astrophysics and Space Science. 220:97-105

From two sets of the spectroscopic observations covering a ten year period we have obtained 59 radial velocities of the chromospherically-active star HD 28591 = V492 Per. It is a G9III single-lined spectroscopic binary with a period of 21.2910 days a

Autor: C M, Riley, M A, Mummert, J, Zhou, R L, Schowen, D G, Vander Velde, M D, Morton, M, Slavik

Publikováno v: Pharmaceutical research. 12(9)

The purposes were to study the kinetics of hydrolysis of 2',3',5'-triacetyl-6-azauridine (1) in aqueous solution (mu = 0.5) and to identify the main intermediates and products of the reaction.A stability indicating isocratic LC assay was used to stud
