A new technique to perform speckle interferometric measurements at J, H, K, L and M wavelengths is described. The time-averaged spatial frequency power spectrum...
Spectroscopy of asteroids can be diagnostic of their surface composition and other properties such as internal structure. The European Space Agency's Gaia...
Spectral analysis of early-type stars using a genetic algorithm based fitting method
We present the first automated fitting method for the quantitative spectroscopy of O- and early B-type stars with stellar winds. The method combines the non-LTE...
Spectral analysis of high resolution near-infrared spectra of ultra cool dwarfs
Aims:We present an analysis of high resolution spectra in the J band of five ultra cool dwarfs from M6 to L0. Methods: We make use of a new ab initio water...
Spectral analysis of the barium central star of the planetary nebula Hen 2-39
Context. Barium stars are peculiar red giants characterized by an overabundance of the elements synthesized in the slow neutron-capture nucleosynthesis (s...
Spectral Analysis of the Gravitational Radiation Emitted by Binary Systems in Moderately Eccentric Orbits - Application to Coalescing Binaries
We obtain the form of the gravitational waves emitted by eccentric binary systems, including general relativistic periastron advance effects. Using the method...
Spectral and radial velocity studies of 5 northern central stars of planetary nebulae
Spectrograms of five bright northern central stars of planetary nebulae (CSPN) are compiled in order to provide spectral descriptions of these stars, with...
Spectral and timing evolution of the bright failed outburst of the transient black hole Swift J174510.8-262411
We studied time variability and spectral evolution of the Galactic black hole transient Swift J174510.8-262411 during the first phase of its outburst. INTEGRAL...
