Stokes inversion techniques are very powerful methods for obtaining information on the thermodynamic and magnetic properties of solar and stellar atmospheres...
Behaviour of Comet 21P/Giacobini-Zinner during the 1998 perihelion
Comet 21P/Giacobini-Zinner was observed from Nov. 8 to Dec. 10, 1998. Pre- and post-perihelion CCD images of the gas (CN, C2) and dust (green and red continua)...
Benchmark stars, benchmark spectrographs. Detailed spectroscopic comparison of ESPRESSO, PEPSI, and HARPS data for Gaia benchmark stars
Context. Gaia benchmark stars are selected to be calibration stars for different spectroscopic surveys. Very high-quality and homogeneous spectroscopic data for...
Benchmark tests of transmission spectroscopy using transiting white dwarfs
Context. Ground-based transit observations are affected by both telluric absorption and instrumental systematics, which can affect the final retrieved...
BeppoSAX observations of the nearby low-mass X-ray binary and fast transient SAX J1819.3-2525
SAX J1819.3-2525 is a nearby X-ray transient which exhibited a fast and large X-ray outburst on Sep. 15, 1999 (Smith et al. 1999). The Wide Field Cameras and...
BeppoSAX Wide Field Cameras observations of six type I X-ray bursters
We have discovered three certain (SAX J1324.5-6313, 2S 1711-339 and SAX J1828.5-1037) and two likely (SAX J1818.7+1424 and SAX J2224.9+5421) new thermonuclear X...
Beryllium abundances in late-type Hyades dwarf stars.
We have observed, with high spectral resolution, the BeII resonance doublet at λ 3131A in five G and K-type main-sequence stars belonging to the Hyades open...
Beryllium abundances in parent stars of extrasolar planets: 16 Cygni A & B and rho (1) CANCRI
The (9) Be ii lambda 3131 Angstroms doublet has been observed in the solar-type stars 16 Cyg A & B and in the late G-type star rho (1) Cnc, to derive their...
Beryllium abundances in stars hosting giant planets
We have derived beryllium abundances in a wide sample of stars hosting planets, with spectral types in the range F7V-K0V, aimed at studying in detail the...
