ALMA Compact Array observations of the Fried Egg nebula. Evidence for large-scale asymmetric mass-loss from the yellow hypergiant IRAS 17163-3907
Galván-Madrid, R.; Olofsson, H.; Justtanont, K. +12 more
Yellow hypergiants are rare and represent a fast evolutionary stage of massive evolved stars. That evolutionary phase is characterised by a very intense mass loss, the understanding of which is still very limited. Here we report ALMA Compact Array observations of a 50''-mosaic toward the Fried Egg nebula, around one of the few Galactic yellow hype…
Suzaku Wide-band All-sky Monitor (WAM) observations of GRBs and SGRs
Yamaoka, Kazutaka; Fukazawa, Yasushi; Hanabata, Yoshitaka +29 more
We will review results for gamma-ray bursts (GRBs) and soft gamma repeaters (SGRs), obtained from the Suzaku Wide-band All-sky Monitor (WAM) which operated for about 10 years from 2005 to 2015. The WAM is a BGO (bismuth germanate: Bi4Ge3O12) lateral shield for the Hard X-ray Detector (HXD), used mainly for rejectin…
Photo-z-SQL: Integrated, flexible photometric redshift computation in a database
Beck, R.; Szalay, A. S.; Csabai, I. +2 more
We present a flexible template-based photometric redshift estimation framework, implemented in C#, that can be seamlessly integrated into a SQL database (or DB) server and executed on-demand in SQL. The DB integration eliminates the need to move large photometric datasets outside a database for redshift estimation, and utilizes the computational c…
Which Bow Shock Theory, Gasdynamic or Magnetohydrodynamic, Better Explains CME Stand-off Distance Ratios from LASCO-C2 Observations ?
Cho, K. -S.; Moon, Y. -J.; Kim, R. -S. +2 more
It is generally believed that fast coronal mass ejections (CMEs) can generate their associated shocks, which are characterized by faint structures ahead of CMEs in white-light coronagraph images. In this study, we examine whether the observational stand-off distance ratio, defined as the CME stand-off distance divided by its radius, can be explain…
The cosmological analysis of X-ray cluster surveys. III. 4D X-ray observable diagrams
Pierre, M.; Faccioli, L.; Clerc, N. +4 more
Context. Despite compelling theoretical arguments, the use of clusters as cosmological probes is, in practice, frequently questioned because of the many uncertainties surrounding cluster-mass estimates.
Aims: Our aim is to develop a fully self-consistent cosmological approach of X-ray cluster surveys, exclusively based on observable quantitie…
Comparison of Solar Fine Structure Observed Simultaneously in Lyα and Mg II h
Auchère, F.; De Pontieu, B.; Schmit, D. +10 more
The Chromospheric Lyman Alpha Spectropolarimeter (CLASP) observed the Sun in H I Lyα during a suborbital rocket flight on 2015 September 3. The Interface Region Imaging Telescope (IRIS) coordinated with the CLASP observations and recorded nearly simultaneous and co-spatial observations in the Mg II h and k lines. The Mg II h and Lyα lines are impo…
The reflectivity of Mars at 1064 nm: Derivation from Mars Orbiter Laser Altimeter data and application to climatology and meteorology
Heavens, N. G.
The Mars Orbiter Laser Altimeter (MOLA) on board Mars Global Surveyor (MGS) made > 108 measurements of the reflectivity of Mars at 1064 nm (R1064) by both active sounding and passive radiometry. Past studies of R1064 neglected the effects of atmospheric opacity and viewing geometry on both active and passive mea…
Polarization Characteristics of Zebra Patterns in Type IV Solar Radio Bursts
Misawa, H.; Masuda, S.; Tsuchiya, F. +4 more
The polarization characteristics of zebra patterns (ZPs) in type IV solar bursts were studied. We analyzed 21 ZP events observed by the Assembly of Metric-band Aperture Telescope and Real-time Analysis System between 2010 and 2015 and identified the following characteristics: a degree of circular polarization (DCP) in the range of 0%-70%, a tempor…
Spectroscopic confirmation of the low-latitude object FSR 1716 as an old globular cluster
Kunder, Andrea; Wojno, Jennifer; Koch, Andreas
Star clusters are invaluable tracers of the Galactic components and the discovery and characterization of low-mass stellar systems can be used to appraise their prevailing disruption mechanisms and time scales. However, owing to significant foreground contamination, high extinction, and still uncharted interfaces of the underlying Milky Way compon…
Diamagnetic depression observations at Saturn's magnetospheric cusp by the Cassini spacecraft
Coates, Andrew J.; Krupp, Norbert; Arridge, Christopher S. +4 more
The magnetospheric cusp is a region where shocked solar wind plasma can enter a planetary magnetosphere, after magnetic reconnection has occurred at the dayside magnetopause or in the lobes. The dense plasma that enters the high-latitude magnetosphere creates diamagnetic effects whereby a depression is observed in the magnetic field. We present ob…
