This paper reports on a near-infrared survey of early-type galaxies designed to provide information on bar strengths, bulges, disks, and bar parameters in a...
Fourier method of determining the rotational velocities in OB stars
Aims:We present a comprehensive study that applies the Fourier transform to a sample of O and early B-type stars (either dwarfs, giants, or supergiants) to...
To understand the physical processes governing accretion discs we can study active galactic nuclei (AGNs), X-ray binary systems (XRBs), and cataclysmic...
The geometric characteristics of dust clouds provide important information on the physical processes that structure such clouds. One of such characteristics is...
Fractional loop delays in adaptive optics modeling and control
This paper revisits the problem of optimal (minimum variance) control for adaptive optics (AO) systems when measurement and command applications are...
Free-floating Planet Mass Function from MOA-II 9 yr Survey toward the Galactic Bulge
We present the first measurement of the mass function of free-floating planets (FFPs), or very wide orbit planets down to an Earth mass, from the MOA-II...
Frequencies and splittings of low-degree solar P modes: results of the Luminosity Oscillations Imager.
The Luminosity Oscillations Imager is a part of the VIRGO instrument to be flown aboard the Solar and Heliospheric Observatory in mid 1995. Using a ground-based...
Frequency dependence of p-mode frequency shifts induced by magnetic activity in Kepler solar-like stars
The variations of the frequencies of the low-degree acoustic oscillations in the Sun induced by magnetic activity show a dependence on radial order. The...
Frequency Redistribution Function for the Polarized Two-term Atom
We present a generalized frequency redistribution function for the polarized two-term atom in an arbitrary magnetic field. This result is derived within a new...
