Sev- eral models have been proposed to explain the accretion at different orbital phases by a spherically arXiv:1507.04274v2 [astro-ph.HE] 18 Jul 2015 symmetric stellar wind from the companion. Aims. The aim of this work is to study both the light curve and orbital phase spectroscopy of this source in the long term. Particularly, the folded light curve and the changes of the spectral parameters with orbital phase to analyse the stellar wind of QV Nor, the mass donor of this binary system.

The Hubble Space Telescope (HST)/Space Telescope Imaging Spectrograph (STIS) contains the only currently operating coronagraph in space that is not trained on the Sun. In an era of extreme-adaptive- optics-fed coronagraphs, and with the possibility of future space-based coronagraphs, we re-evaluate the con- trast performance of the STIS CCD camera. The 50CORON aperture consists of a series of occulting wedges and bars, including the recently commissioned BAR5 occulter. We discuss the latest procedures in obtaining high-contrast imaging of circumstellar disks and faint point sources with STIS.

  • Large-Angle Observatory with Energy Resolution for Synoptic X-Ray Studies (LOBSTER-SXS) ∗ Paul Gorenstein , Harvard-Smithsonian Center for Astrophysics, 60 Garden St
    Large-angle OBServaTory with Energy Resolution for Synoptic X-ray Studies (LOBSTER-SXS) ∗ Paul Gorenstein , Harvard-Smithsonian Center for Astrophysics, 60 Garden St. MS-4, Cambridge, MA USA 02138 ABSTRACT The soft X-ray band hosts a larger, more diverse range of variable sources than any other region of the electromagnetic spectrum. They are stars, compact binaries, SMBH’s, the X-ray components of Gamma-Ray Bursts, their X-ray afterglows, and soft X-ray flares from supernova. We describe a concept for a very wide field (~ 4 ster) modular hybrid X-ray telescope system that can measure positions of bursts and fast transients with as good as arc second accuracy, the precision required to identify fainter and increasingly more distant events. The dimensions and materials of all telescope modules are identical. All but two are part of a cylindrical lobster-eye telescope with flat double sided mirrors that focus in one dimension and utilize a coded mask for resolution in the other. Their positioning accuracy is about an arc minute. The two remaining modules are made from the same materials but configured as a Kirkpatrick-Baez telescope with longer focal length that focuses in two dimensions. When pointed it refines the hybrid telescope’s arc minute positions to an arc second and provides larger effective area for spectral and temporal measurements. Above 10 keV the mirrors act as an imaging collimator with positioning capability. For short duration events this hybrid focusing/coded mask system is more sensitive and versatile than either a 2D coded mask or a 2D lobster-eye telescope.

Schattenburg* Kavli Institute for Astrophysics and Space Research, Massachusetts Institute of Technology, 77 Massachusetts Avenue, Cambridge, Massachusetts 02139, USA *Corresponding author: [email protected] Received 11 March 2020; revised 21 April 2020; accepted 23 April 2020; posted 23 April 2020 (Doc. ID 392479); published 27 May 2020 Astronomical imaging with micro-arcsecond (µas) angular resolution could enable breakthrough scientific discov- eries. Previously proposed µas x-ray imager designs have been interferometers with limited effective collecting area. Here we describe x-ray telescopes achieving diffraction-limited performance over a wide energy band with large effective area, employing a nested-shell architecture with grazing-incidence mirrors, while matching the optical path lengths between all shells. We present two compact nested-shell Wolter Type 2 grazing-incidence telescope designs for diffraction-limited x-ray imaging: a micro-arcsecond telescope design with 14 µas angular resolution and 2.9 m2 of effective area at 5 keV photon energy (λ D 0.25 nm), and a smaller milli-arcsecond telescope design with 525 µas resolution and 645 cm2 effective area at 1 keV (λ D 1.24 nm). We describe how to match the optical path lengths between all shells in a compact mirror assembly and investigate chromatic and off-axis aberrations. Chromatic aberration results from total external reflection off of mirror surfaces, and we greatly mitigate its effects by slightly adjusting the path lengths in each mirror shell.

  • Multiwavelength Challenges in the Fermi Era
    71h AGILE Workshop: The Bright -y-ray Sky Multiwavelength Challenges in the Fermi Era D. J. THOMPSON' 'NASA Goddard Space Flight Center, Greenbelt, MD 20771 USA on behalf of the Fermi Large Area Telescope Collaboration ABSTRACT. The gamma-ray surveys of the sky by AGILE and the Fermi Gamma-ray Space Telescope offer both opportunities and challenges for multiwavelength and multi-messenger studies. Gamma-ray bursts, pulsars, binary sources, flaring Active Galactic Nuclei, and Galactic transient sources are all phenomena that can best be studied with a wide variety of instruments simultaneously or contemporaneously. From the gamma-ray side, a principal challenge is the latency from the time of an astrophysical event to the recognition of this event in the data. Obtaining quick and complete multiwavelength coverage of gamma-ray sources of interest can be difficult both in germs of logistics and in terms of generating scientific interest. 1. Introduction - The Multiwavelength Revolution The process of astrophysical research has changed dramatically in the past 30 years, and the inclusion of multiwavelength studies has been an important aspect of that change. As an example of the growing importance of studies that reach beyond a single wavelength, consider this simple literature search using NASA ADS (http://adsabs.harvard.edu/ads-abstracts.html) . The search was for the word "Multiwavelength" in titles for each of four years spanning three decades. The result is shown in Table 1. TABLE I Papers with "Multiwavelength" in the Title Year Papers 1976 0 1986 2 1996 58 2006 97 Even considering the normal growth of scientific publications, the increase in multi- wavelength research has been dramatic.

  • Systematic Survey of Short X-Ray Transients by MAXI
    Tokyo Institute of Technology Doctoral Thesis Systematic Survey of Short X-ray Transients by MAXI Author: Supervisor: Ryuichi Usui Prof. Nobuyuki Kawai A thesis submitted in fulfilment of the requirements for the degree of Doctor of Physics in the Kawai Grp. Department of Physics March 2014 Abstract We present the systematic search of short X-ray transients for the 1327-day data obtained with MAXI (Monitor of All-sky X-ray Image). Short X-ray transients have been detected by past X- ray/γ-ray satellites in large-sky surveys, and their temporal, spectral and spatial characteristics have been studied. They include Gamma-Ray Bursts (GRBs), X-ray bursts from neutron-star binaries, X-ray flares of active stars and X-ray short activities of blazars. In addition shock breakouts of supernovae and tidal disruption events at the center of a nearby galaxy have been also reported recently. Discovery of new class of transients should also benefit astrophysics. To perform the search we used the data obtained by the Gas Slit Camera (GSC) of MAXI, an X-ray detector that monitors almost the whole sky with the arc-like field of view every 92- min orbital period of the International space station. While the search of transients using the GSC data has been already performed in the past, its method required detailed modeling of the instrument and the background, and the propagation of errors and the evaluation of significance was not trivial. In addition, the used data covered only the first 15-month of operation. Thus, we newly develop a simple and versatile analysis program, and conducted the search for short X-ray transients from the MAXI-GSC data obtained since October 2009 until May 2013.
