    MOSFIRE is a NIR multi-object spectrograph in operation at the Cassegrain focus of the Keck I telescope since MOSFIRE was designed and built by a collaboration among UCLA, CIT, and UCSC under the direction of co-Principal Investigators Ian McLean and Chuck Steidel. spectra during the portion of VV Pup's orbit when the accreting magnetic pole of the white dwarf can be seen show an increasing continuum level as the accretion spot becomes more directly visible. The most prominent features in the spectrum are the O VI & lambda; & lambda;, emission by: 8.

    We report on a simultaneous NuSTAR and Swift observation of the neutron star low-mass X-ray binary 4U We identified and removed four Type I X-ray bursts during the observation in order to study the persistent emission. The continuum spectrum is hard and described well by a blackbody with kT = keV and a cutoff power law with Γ = , and a cutoff temperature of 25 by:

RS Ophiuchi (RS Oph) is a recurrent nova system approximately 5, light-years away in the constellation Ophiuchus. In its quiet phase it has an apparent magnitude of about It has been observed to erupt in,and and reached about magnitude 5 on average.

RS Oph belongs to the cataclysmic variable (CV) class of stars, and is further classified as belonging to a smaller, seemingly "exclusive" group of CVs termed recurrent novae (NR) - of which there are only 7 confirmed members.

This class of stars has a physical system similar to the nova and dwarf nova types of. variable star in the constellation Canes Venatici.

Variations of the orbital parameters and of the insolation If we ignore the role of the atmosphere, the insolation at a particular time and location at the Earth's surface is a function of the Sun-Earth distance and the cosine of the solar zenith distance (Eq.

).These two variables can be computed from the time of day, the latitude, and the characteristics of the Earth's orbit. The sun's radiance is the large spike at, which corresponds to looking upward at a zenith angle of 40 deg in the azimuthal direction, where the sun was located in this simulation.

The smaller spike at is the sun's specular reflection, seen looking downward and towards the sun. The ratio of the sun's specular reflectance at nm (, obtained from the radiance values tabulated in the data file.

We used a new method for the estimation of the elements of the visual orbit with no a priori information on the orbital parameters (PD94) and an automated Lehmann-Filhés procedure for determining the elements of the spectroscopic orbit.

The results of both computations are being illustrated and by: 1. The microphone signal was fed to a custom-made, real-time song recognizer that detected the first stereotypic syllable of song motifs using a two-layer neural network trained on.

It is thought to be about 2 Billion years old and classified as a RS Canum Venaticorum variable type star. Star A is a spectroscopic binary, with star Ab orbiting from to AU, making any habitable planetary orbit unstable.

Star B is another yellow dwarf star, about 90% as massive and as large as the Sun. By application of super twisted nematic liquid crystals to spatial light modulators, readout light can be modulated sufficiently even if the photoconductive layer is as thin as 1 μm. This is in contrast to the case of conventional spatial light modulators, which require a thick photoconductive layer (>10 μm).

Also, the sensitivity is greatly increased (2 μW/cm2 at the applied sinusoidal. A technique that combines spectroscopy and microscopy Definition from Wiktionary, the free dictionary.

The preface avoids the taboo word hong by omitting the last. According to Vizier, this is an A2 Ib star, with an implied M V ~ Given that V =d ~ 8 kpc. The BVR photometry suggests an early or middle A-type star, around A V or an earlier-type giant or supergiant.

The JHK photometry suggests an early A-type star, and the B-R/J-K and R-J/J-K diagrams suggest a middle A-type star.

A medium-resolution Fourier-transform spectrometer for ground-based observation of astronomical sources at near-millimeter and submillimeter wavelengths is described.

The steps involved in measuring and calibrating astronomical spectra are elaborated. The spectrometer is well suited to planetary spectroscopy, and initial measurements of the intrinsic brightness temperature spectra of Uranus.
