Using globular clusters to test gravity in the weak acceleration regime: NGC 6171

Riccardo Scarpa, Gianni Marconi, Roberto Gilmozzi

As part of an ongoing program to test Newton's law of gravity in the low acceleration regime using globular clusters, we present here new results obtained for NGC 6171. Combining V…

Taking the pulse of the shortest orbital period binary system RX J0806.3+1527

G. L. Israel, S. Covino, S. Dall'Osso +8

RX J0806.3+1527 is thought to be a 321s orbital period (the shortest known) double white dwarf binary system. According to the double degenerate binary (DDB) scenario this source i…

Unveiling the multi-wavelength phenomenology of Anomalous X-ray Pulsars

GianLuca Israel, Luigi Stella, Stefano Covino +6

During 2002-2003 the number of IR-identified counterparts to the Anomalous X-ray Pulsars (AXPs) has grown to four (4U0142+614, 2E2259+584, 1E 1048-59 and 1RXS J170849-400910) out o…

Sgr dSph: a bridge between Dwarf Galaxies and DLAs?

L. Sbordone, P. Bonifacio, G. Marconi +2

We present abundances for 12 giants in the Sagittarius Dwarf Spheroidal Galaxy (Sgr dSph) obtained from VLT - UVES spectra. Moving on a short period, polar orbit around the Milky W…

Chemical abundances in Terzan 7 from UVES spectra

L. Sbordone, P. Bonifacio, G. Marconi +1

We present chemical abundances for Mg, Si, Ca and Fe for three red giants in the sparse globular cluster Terzan 7, physically associated to the Sagittarius Dwarf Spheroidal Galaxy…

Near-Infrared photometry of LMC cluster Reticulum

M. Dall'Ora, G. Bono, J. Storm +11

We present near-infrared (JKs) time series data of the Large Magellanic Cloud (LMC) cluster Reticulum. The observing strategy and data reduction (DAOPHOTII/ALLFRAME) allowed us to…
