Timing and spectral study of XB 1254-690 using new RXTE PCA data
accretion, accretion disks — methods: data analysis — stars: neutron— techniques: miscellaneous — X-rays: binaries — X-rays: individual
2011/10/12
We have analyzed the new Rossi X-ray Timing Explorer Proportional Counter Array data of the atoll neutron star (NS) low-mass X-ray binary (LMXB) system XB 1254-690. The colour-colour diagram shows tha...
Infrared two-colour diagrams for AGB stars using AKARI, MSX, IRAS and NIR data
stars: AGB and post-AGB - circumstellar matter - infrared: stars - dust extinction - radiative transfer
2011/10/12
Using a revised version of the catalog of AGB stars by Suh & Kwon (2009), we present various infrared two-colour diagrams (2CDs) for 3003 O-rich, 1168 C-rich, 362 S-type and 35 silicate carbon stars i...

While the Swift satellite is primarily designed to study gamma-ray bursts, its ultraviolet and optical imaging and spectroscopy capabilities are also being used for a variety of scientific programs. I...
Infrared Spectroscopy of Comet 73P/Schwassmann-Wachmann 3 using the Spitzer Space Telescope
Infrared Spectroscopy Comet using Spitzer Space Telescope
2011/10/8
We have used the Spitzer Space Telescope Infrared Spectrograph (IRS) to observe the 5-37 micron thermal emission of comet 73P/Schwassmann-Wachmann 3 (SW3), components B and C. We obtained low spectral...
