Research Developments in Li-Paczyński Novae (II): Observational Aspect

DOI: 10.1016/j.chinastron.2016.10.007 Bibcode: 2016ChA&A..40..439W

Wang, Shan-qin; Dai, Zi-gao; Wu, Xue-feng

Since the LP-Nova models were proposed, and the short gamma-ray burst (SGRB) afterglows were confirmed, people have actively made searches for the evidence of the existence of LP-Novae among the optical (or near-infrared) counterparts of SGRBs. In this paper, we first summarize these observational progresses before 2012 in Section 2. In Section 3 …

Modeling the spectral response for the soft X-ray imager onboard the ASTRO-H satellite

DOI: 10.1016/j.nima.2016.03.071 Bibcode: 2016NIMPA.831..415I

Uchida, Hiroyuki; Hayashida, Kiyoshi; Nakajima, Hiroshi +20 more

The ASTRO-H satellite is the 6th Japanese X-ray astronomical observatory to be launched in early 2016. The satellite carries four kinds of detectors, and one of them is an X-ray CCD camera, the soft X-ray imager (SXI), installed on the focal plane of an X-ray telescope. The SXI contains four CCD chips, each with an imaging area of 31 mm × 31 mm , …

Variation in the Width of Transition Region Network Boundaries

DOI: 10.1007/s11207-016-0991-1 Bibcode: 2016SoPh..291.3519R

Raju, K. P.

The transition region network seen in solar extreme ultraviolet (EUV) lines is the extension of the chromospheric network. The network appears as an irregular web-like pattern over the solar surface outside active regions. The average width of transition region network boundaries is obtained from the two-dimensional autocorrelation function of SOl…

Searching for the HR 8799 Debris Disk with HST/STIS

DOI: 10.3847/0004-637X/823/2/149 Bibcode: 2016ApJ...823..149G

Venn, K.; Matthews, B.; Lawler, S. +3 more

We present a new algorithm for space telescope high contrast imaging of close-to-face-on planetary disks called Optimized Spatially Filtered (OSFi) normalization. This algorithm is used on HR 8799 Hubble Space Telescope (HST) Space Telescope Imaging Spectrograph (STIS) coronagraphic archival data, showing an over-luminosity after reference star po…

Transport of Solar Wind H⁺ and He⁺⁺ Ions across Earth’s Bow Shock

DOI: 10.3847/2041-8205/825/2/L27 Bibcode: 2016ApJ...825L..27P

Liu, Y.; Dandouras, I.; Rème, H. +10 more

We have investigated the dependence of mass, energy, and charge of solar wind (SW) transport across Earth’s bow shock. An examination of 111 crossings during quiet SW in both quasi-perpendicular and quasi-parallel shock regions shows that 64 crossings had various degrees of heating and thermalization of SW. We found 22 crossings where the SW speed…

A traveling feature in Saturn's rings

DOI: 10.1016/j.icarus.2016.06.012 Bibcode: 2016Icar..279..100R

Esposito, Larry W.; Sremčević, Miodrag; Albers, Nicole +3 more

The co-orbital satellites of Saturn, Janus and Epimetheus, swap radial positions every 4.0 years. Since Cassini has been in orbit about Saturn, this has occurred on 21 January in 2006, 2010, and 2014. We describe the effects of this radial migration in the Lindblad resonance locations of Janus within the rings. When the swap occurs such that Janus…

Transport and Distribution of Hydroxyl Radicals and Oxygen Atoms from H₂O Photodissociation in the Inner Coma of Comet 67P/Churyumov–Gerasimenko

DOI: 10.1007/s11038-016-9481-6 Bibcode: 2016EM&P..117...23L

Ip, Wing-Huen; Thomas, Nicolas; Lai, Ian-Lin +5 more

With a combination of the Direct Simulation Monte Carlo (DSMC) calculation and test particle computation, the ballistic transport process of the hydroxyl radicals and oxygen atoms produced by photodissociation of water molecules in the coma of comet 67P/Churyumov–Gerasimenko is modelled. We discuss the key elements and essential features of such s…

Ocular Shock Front in the Colliding Galaxy IC 2163

DOI: 10.3847/0004-637X/831/2/161 Bibcode: 2016ApJ...831..161K

Brinks, Elias; Struck, Curtis; Elmegreen, Bruce G. +5 more

ALMA observations in the ¹²CO J=1\to 0 line of the interacting galaxy pair IC 2163 and NGC 2207 at 2″ × 1.″5 resolution reveal how the encounter drives gas to pile up in narrow, ∼1 kpc wide, “eyelids” in IC 2163. IC 2163 and NGC 2207 are involved in a grazing encounter, which has led to the development in IC 2163 of an eye-shaped (ocula…

A Model for the Dust Envelope of the Silicate Carbon Star IRAS 09425-6040

DOI: 10.3847/0004-637X/819/1/61 Bibcode: 2016ApJ...819...61S

Suh, Kyung-Won

IRAS 09425-6040 (I09425) is a silicate carbon star with conspicuous crystalline silicate and water-ice features and emission excesses in the far-infrared and millimeter (mm) wavelength ranges. To understand properties of the dust envelope of I09425, we propose a physical model based on the observations and known properties of asymptotic giant bran…

We present a comparison of the Gaia DR1 samples of pulsating variable stars - Cepheids and RR Lyr type - with the OGLE Collection of Variable Stars aiming at the characterization of the Gaia mission performance in the stellar variability domain.

Out of 575 Cepheids and 2322 RR Lyr candidates from the Gaia DR1 samples located in the OGLE footp…
