Description
An RXTE observation of 4U 1636-536 taken on March 10th, 2009, revealed two type I X-ray bursts from this well studied neutron star low-mass X- ray binary (NS-LMXB). The recurrence time (wait time) between the two events, 5.4 minutes, is the shortest observed in any NS-LMXB. The average spectrum exhibited by both bursts was thermal. We performed time- resolved spectroscopy along the bursts, using a black body model and an absorbing column density of 0.3e22 cm-2 (Fiocchi et al.

    HARMONI at ELT: HIPOTEC electronics and control system
    HARMONI is the first light visible and near-IR integral field spectrograph for the ELT. It covers a large spectral range from 470nm to 2450nm with resolving powers from 3300 to 18000 and spatial sampling from 60 mas to 4 mas. It can operate in two Adaptive Optics modes - SCAO (including a High Contrast capability) and LTAO - or with NOAO. The

    GTCAO low-frequency tip-tilt offload to M2
    GTCAO is the instrument that implements Adaptive Optics on GTC. For atmospheric turbulence correction, GTCAO uses a deformable mirror. Unlike other AO systems, GTCAO does not include a dedicated mirror for low-frequency tip-tilt (TT) correction. In the absence of dedicated correction, the TT components of atmospheric turbulence are corrected by the
