The 10-Micron Limb Darkening of Venus
In June 1964, several diametric profiles of the 8to 14-/z flux from Venus were obtained with the 200-inch Hale telescope operated in the east-arm Cassegrainian mode. These data were recorded with a photometer system described previously [Westphal et al., 1963] as part of a surveillance program [Westphal et al., 1965]. Venus was near inferior conjunction and 52.2 sec of arc in apparent diameter,...
متن کاملAsymmetries in Limb Darkening
The cause of the asymmetries in limb darkening reported by Neckel and Labs (1987) is discussed on the basis of new, stray-light-free observations, and found to be of instrumental origin.
متن کاملWavelength dependency of the Solar limb darkening
A single parameter model of the mean Solar limbdarkening is presented. This empirical law has the advantage to represent the limb darkening over a large spectrum at least as well as a quadratic or logarithmic law. Since it is less sensitive than high degree polynomial laws, it is recommended for subsequent analysis of average limb-darkening variations and comparisons.
متن کاملMeasuring Stellar Limb Darkening by Gravitational Microlensing
Observations of microlensing transit events can be used to measure the limb darkening of the lensed star. We discuss the advantages and drawbacks of several microlensing light curve inversion methods. The method of choice in this work is inversion by means of decomposition of the stellar surface brightness profile. We construct an ideal basis by principal component analysis of brightness profil...
متن کاملLimb-darkening and radii of M-type Mira models
Monochromatic limb-darkening and monochromatic radii predicted by the M-type Mira models of Bessell et al. (1996) and by new models described in Sect. 2 were computed for selected typical bandpasses used in interferometric and lunar occultation work. The new self-excited pulsation model series have periods and luminosities similar to o Ceti and R Leonis and comprise both fundamental (1 M , 1.2 ...
