The unusual radio transient in M82: an SS 433 analogue?
stars:radio:continuum – stars:X-rays:binaries – Galaxies:individual:M82– X-rays:galaxies
2011/10/19
In this paper we discuss the recently discovered radio transient in the nuclear region of M\,82. It has been suggested that this source is an X-ray binary, which, given the radio flux density, would r...

A new prediction error correction scheme based on 74 circulation characteristics data provided by Weather Diagnostic Forecasting Division of National Climate Center, which is designed to develop the O...
Differential rotation on the young solar analogue V889 Herculis
Solar and Stellar Astrophysics (astro-ph.SR)
2011/1/6
V889 Herculis is one of the brightest single early-G type stars, a young Sun, that is rotating fast enough (P_rot =1.337 days) for mapping its surface by Doppler Imaging. The 10 FOCES spectra collecte...
The HARPS search for southern extra-solar planets. XXIV. Companions to HD 85390, HD 90156 and HD 103197: A Neptune analogue and two intermediate mass planets
Earth and Planetary Astrophysics (astro-ph.EP)
2010/12/24
We report the detection of three new extrasolar planets orbiting the solar type stars HD 85390, HD 90156 and HD 103197 with the HARPS spectrograph mounted on the ESO 3.6-m telescope at La Silla observ...
Physicists in Israel have created a black–hole analogue that can trap sound in the same way an astrophysical black hole can trap light. The system, which comprises a “density-inverted Bose–Einstein co...
