Spectral modelling of theαVirginis (Spica) binary system

Fluidization of Initialty Segregased Equidensity Binary System

Fluidization of initially segregated binary mixtures has been investigated for particle systems of the same material. This paper reports experiments conducted in 0.055m diameter fluidizes bed for binary mixtures composed of sands whose sizes ranged from 450 to 1450mm. An empirical relationship, Utf = 0.95 UF (dR)0.87, was derived in terms of the minimum fluidization of the smaller particle, UF ...

Simultaneous MOST photometry and high-resolution spectroscopy of Spica, a binary system with a massive β Cephei star component

We present the data from a unique observational study of Spica, a binary system with a primary component of β Cephei type. We exploit simultaneous high-resolution spectroscopic observations and high-precision photometry obtained by the MOST satellite. By disentangling the spectra of this binary, we get an accurate determination of the orbit. Future work includes a full seismic analysis of the s...

SPICA and Its Instrumentation

SPICA (Space Infrared Telescope for Cosmology and Astrophysics) is an astronomical mission optimized for midand far-infrared astronomy with a cryogenically cooled 3.5 m telescope. Its high spatial resolution and unprecedented sensitivity in the midand far-infrared will enable us to address a number of key problems in present-day astronomy, ranging from the star-formation history of the universe...
