چکیده
We calculate the total γ-ray line emission at ∼450 keV that accompanies 7 Li and 7 Be production by cosmic-ray interactions, including the delayed line emission at 0.478 MeV from 7 Be radioactive decay. We present a new γ-ray spectroscopic test which has the potential to give direct information on the nature of the interstellar regions into which 7 Be ions propagate and decay. Finally, we evaluate the intensity of the predicted diffuse emission from the central radian of the Galaxy.

The production of Li and Be during the explosive hydrogen–burning that occurs in nova explosions is computed by means of a hydrodynamic code able to treat both the accretion and the explosion stages. Large overproduction factors with respect to solar abundances are obtained, the exact value depending mainly on the chemical composition of the envelope. Although the final ejected masses are small...

We report high-resolution spectroscopic observations of the young star HD 34700, which confirm it to be a double-lined spectroscopic binary. We derive an accurate orbital solution with a period of 23.4877 ± 0.0013 days and an eccentricity of e = 0.2501 ± 0.0068. The stars are found to be of similar mass (M 2 /M 1 = 0.987 ± 0.014) and luminosity. We derive also the effective temperatures (5900 K...

Production of the light nuclides D, 3 He, 4 He, and 7 Li in their currently inferred primordial abundances by standard, homogeneous big bang nucle-osynthesis (SHBBN) would imply a baryon fraction of the cosmic closure density Ω b in the range: 0.04 ≤ Ω b h 2 50 ≤ 0.08 (1) where h 50 is the Hubble constant in units of 50 km s −1 Mpc −1 [1], [2].

We present the technical details of the gamma-ray burst (GRB) alert system of the Katzman Automatic Imaging Telescope (KAIT) at Lick Observatory, and the successful observations of the GRB 020813 optical afterglow with this system. KAIT responds to GRB alerts robotically, interrupts its pre-arranged program, and takes a sequence of images for each GRB alert. A grid-imaging procedure is used to ...
