The Visual Orbit of • Pegasi
We have determined the visual orbit for the spectroscopic binary • Pegasi with interferometric visibility data obtained by the Palomar Testbed Interferometer in 1997. • Peg is a double-lined binary system whose minimum masses and spectral typing suggests the possibility of eclipses. Our orbital and component diameter determinations do not favor the eclipse hypothesis : the limb-to-limb separati...
متن کاملThe Planet around 51 Pegasi
Doppler measurements of 51 Pegasi have been made from 1995 October through 1996 August, with a precision of 5 m s~1. We Ðnd a period of 4.231 days, a velocity amplitude of 56^ 1 m s~1, and a velocity curve that is essentially sinusoidal, all in excellent agreement with Mayor & Queloz. The only viable interpretation is a companion having minimum mass, m sin i \ 0.45 in a circular orbit of MJupit...
متن کاملCalibration of ι Pegasi system
Recent observations provide determinations of individual masses, chemical composition and metallicity of the components of the spectroscopic and interferometric binary ι Peg (Boden et al. 1999). Using updated physics, to calibrate the system, we have computed using the stellar evolutionary code CESAM (Morel 1997), evolutionary sequences of stellar models with the masses of ι Peg A 1.326M and ι ...

متن کاملDmd065755 1891..1904
The cytochrome P450 2C19 (CYP2C19) enzyme plays an important role in the metabolism of many commonly used drugs. Relatively little is known about CYP2C19 inhibitors, including compounds of natural origin, which could inhibit CYP2C19, potentially causing clinically relevant metabolism-based drug interactions. We evaluated a series (N = 49) of structurally related plant isoquinoline alkaloids for...
