Rotational Velocities of Very Low Mass Binaries
We present rotational velocities for individual components of eleven very low mass (VLM) binaries with spectral types between M7.5 and L4. These results are based on observations taken with the near-infrared spectrograph, NIRSPEC, and the Keck II laser guide star adaptive optics (LGS AO) system. The binaries were targeted as part of a dynamical mass program, and their orbital inclinations are u...
متن کاملThe effect of variation of stellar dispersion velocities by the galactic latitude in interpreting gravitational microlensing observations
Our galaxy is a spiral galaxy and its stars are mostly in a thin disk and rotate around the galactic center. The vertical component of the dispersion velocity of stars is a function of the galactic latitude and decreases with increasing it. In the galactic Besancon model, this dependence is ignored and they just consider the dependence of dispersion velocity on the stellar age. Becanson model i...
متن کاملUnderstanding A-type supergiants II. Atmospheric parameters and rotational velocities of Galactic A-type supergiants
We present the second paper of a series whose aim is to perform a global study of Galactic A-supergiants. Very little work has been carried out to determine the stellar parameters of these stars. This is illustrated with a brief review of some previous works. In this paper we analyze the determination of absolute magnitudes, spectral types and atmospheric parameters using the most recent Kurucz...
متن کاملP113: Predicting Body Image Anxiety Based on Positive and Negative Perfectionism and Body Mass Index
Body image is an internal representation of the external appearance which includes physical and perceptual aspects and attitudes toward them. Body image anxiety can cause weight problems. In addition, perfectionism, the trend or effort to be perfect and flawless can cause extreme thinking and self-criticism. Perfectionism can provoke anxiety and concerns for body image and weight, especially in...
متن کاملExact Solutions for Some Nuclear Many-Body Problems
Exact solutions for eigenvalues and eigenfunctions of some nuclear many-body systems are found by using an infinite-dimensional, Lie-algebraic approach based on the corresponding Bethe ansatz. Applications of the theory, including solutions of some nuclear pairing problems and U(5) W SO(6) transitional Hamiltonians of the interacting boson model, are given. The relationship between this new met...
