Spectroscopy of brown dwarf candidates in IC 348 and the determination of its substellar IMF down to planetary masses

C. Alves de Oliveira, E. Moraux, J. Bouvier +4

Context. Brown dwarfs represent a sizable fraction of the stellar content of our Galaxy and populate the transition between the stellar and planetary mass regime. There is however…

Formation and Radiative Feedback of First Objects and First Galaxies

Masayuki Umemura, Hajime Susa, Kenji Hasegawa +2

First, the formation of first objects driven by dark matter is revisited by high-resolution hydrodynamic simulations. It is revealed that dark matter haloes of ~10^4M_sun can produ…

Nitrogen hydrides in interstellar gas II. Analysis of Herschel/HIFI observations towards W49N and G10.6-0.4 (W31C)

C. M. Persson, M. De Luca, B. Mookerjea +14

We have used the Herschel-HIFI instrument to observe interstellar nitrogen hydrides along the sight-lines towards W49N and G10.6-0.4 in order to elucidate the production pathways l…

Capture of non-relativistic particles in eccentric orbits by a Kerr black hole

Clifford M. Will

We obtain approximate analytic expressions for the critical value of the total angular momentum of a non-relativistic test particle moving in the Kerr geometry, such that it will b…

The relativistic pulsar-white dwarf binary PSR J1738+0333 II. The most stringent test of scalar-tensor gravity

Paulo C. C. Freire, Norbert Wex, Gilles Esposito-Farèse +7

(abridged) We report the results of a 10-year timing campaign on PSR J1738+0333, a 5.85-ms pulsar in a low-eccentricity 8.5-hour orbit with a low-mass white dwarf companion (...) T…

Modelling the black hole silhouette in Sgr A* with ion tori

Odele Straub, Frederic H. Vincent, Marek A. Abramowicz +2

We calculate the "observed at infinity" image and spectrum of the accretion structure in Sgr A*, by modelling it as an optically thin, constant angular momentum ion torus in hydrod…
