Descripción
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.

    NEOMIR: ESA's space-based infrared mission for NEO detection and early warning
    The Near-Earth Object Mission in the Infra-Red (NEOMIR) is the first ESA's space-based mission fully dedicated to discovering near-Earth objects (NEOs), with a focus to detect and raise early warning for the smaller objects that are coming from the Sun direction, thus nearly impossible to be detected by ground-based optical survey. NEOMIR is

    Upgrading the polarisation modulation unit of the Gregor Infrared Spectrograph
    The Gregor Infrared Spectrograph (GRIS) is installed at the Gregor telescope at Observatorio del Teide, Spain. The instrument started observations in 2012 and underwent several upgrades in the following years. Currently, it is experiencing the most significant upgrade so far, which includes, among other things, adding two optical channels to

    Small-ELF Telescope opto-mechanical system: progress on design, manufacturing, and tensegrity prototyping
    Small-ELF (SELF) is a 3.5-meter telescope currently entering the manufacturing phase and will serve as a technology precursor for the much larger telescope named ELF (Exo-Life Finder). The primary objective of the proposed design approach is to to radically improve the system's capabilities for the detection of biomarkers and life in the
