Spectral signature of near-surface damage in CdTe X-ray detectors
Grimm, O.
Knowledge of the response matrix of an X-ray detector is an important prerequisite for efficient use. This matrix is usually complicated due to the multitude of effects that determine the photon interaction and energy detection processes. Consequently, assembly of a response matrix often proceeds via simulation, modelling features of the detector …
Editorial: Solar Wind at the Dawn of the Parker Solar Probe and Solar Orbiter Era
Lapenta, Giovanni; van Driel-Gesztelyi, Lidia; Zhukov, Andrei
Solar Wind 15 brought together almost 250 experts from all continents of the world to discuss the current trends and future perspectives of the research on the Sun and its solar wind. The present article collection recaptures some of the highlights of their contributions.
Tidal Currents Detected in Kraken Mare Straits from Cassini VIMS Sun Glitter Observations
Sotin, Christophe; Barnes, Jason W.; Soderblom, Jason M. +3 more
We present Cassini Visual and Infrared Mapping Spectrometer (VIMS) observations of sun glitter—wave-induced reflections from a liquid surface offset from a specular point—on Kraken Mare. sun glitter reveals rough sea surfaces around Kraken Mare, namely the coasts and narrow straits. The sun glitter observations indicate wave activity driven by the…
Changes in a Dusty Ringlet in the Cassini Division after 2010
Bridges, Bill; Hedman, Mathew
A dusty ringlet designated R/2006 S3, also known as the "Charming Ringlet," is located around 119,940 km from the center of Saturn within the Laplace Gap in the Cassini Division. Prior to 2010, the ringlet had a simple radial profile and a predictable eccentric shape with two components, one forced by solar radiation pressure and the other freely …
The Clusters AgeS Experiment (CASE). Variable Stars in the Field of the Globular Cluster NGC 3201 - a Supplement
Thompson, I. B.; Rozyczka, M.; Pych, W. +1 more
We report the detection of 20 new variables in the field of NGC 3201. Among them there are 15 confirmed cluster members. Follow-up observations are desirable for two blue stragglers with variable light curves (probably resulting from magnetic activity), and for a yellow straggler coinciding with a Chandra X-ray source. Two of the eclipsing binarie…
Absorption-line Abundances in the SMC-like Galaxy UGC 5282: Evidence of ISM Dilution from Inflows on Kiloparsec Scales
Bowen, David V.; Tripp, Todd M.; Jenkins, Edward B. +4 more
We present a Hubble Space Telescope Cosmic Origins Spectrograph spectrum of the QSO SDSS J095109.12+330745.8 ( ${z}_{\mathrm{em}}=0.645$ ) whose sightline passes through the SMC-like dwarf galaxy UGC 5282 ( ${M}_{B}=-16.0$ , cz = 1577 km s-1), 1.2 kpc in projection from the central H II region of the galaxy. Damped Lyα (DLA) absorption …
Study of Coronal Mass Ejections Succeeding the Associated X-Ray and γ-Ray Burst Solar Flares
Abdel-Sattar, Walid; Mawad, Ramy
This study is dedicated to the investigation of the characteristics of CMEs following the associated X-ray and γ-ray burst solar flares. Investigated 14786 CME events and 5092 Gamma Burst Monitor (GBM) solar flare events recorded during the solar period 2008–2017, found 503 (about 10%) CME events associated with GBM post-flare events (hereafter, G…
Evryscope-South Survey of Upper- and Pre-main Sequence Solar Neighborhood Stars
Law, Nicholas M.; Corbett, Hank; Gonzalez, Ramses +5 more
Using photometric data collected by Evryscope-South, we search for nearby young variable systems on the upper main sequence (UMS) and pre-main sequence (PMS). The Evryscopes are all-sky high-cadence telescope arrays operating in the Northern and Southern hemispheres. We base our search on a Gaia-selected catalog of young neighborhood upper- and pr…
A Binary Star in the Superbubble N160 in the Large Magellanic Cloud
Chu, You-Hua; Li, Chuan-Jui; Ishioka, Ryoko +2 more
We have made a spectroscopic investigation of the nature of 053949.17-693747.4, a blue star with mid-infrared excess, projected within a superbubble in the H II complex N160 in the Large Magellanic Cloud (LMC). Analyses of photometric and spectrophotometric data of this star indicate that it is an O7 ± 1 V in the LMC. The radial velocity of this s…
The fate of binary stars hosting planets upon interaction with Sgr A* black hole
Capuzzo-Dolcetta, R.; Davari, N.
Our Galaxy hosts a very massive object at its centre, often referred to as the supermassive black hole Sgr A*. Its gravitational tidal field is so intense that it can strip apart a binary star passing its vicinity and accelerate one of the components of the binary as hypervelocity star (HVS) and grab the other star as S-star. Taking into considera…
