How a Cartoon Series Helped the Public Care about Rosetta and Philae
Bauer, M.; McCaughrean, M.; O'Flaherty, K. S. +5 more
Once upon a time... is a series of short cartoons that have been developed as part of the European Space Agency's communication campaign to raise awareness about the Rosetta mission. The series features two anthropomorphic characters depicting the Rosetta orbiter and Philae lander, introducing the mission story, goals and milestones with a fairy- …
Multi-spectral observations of flares
Zuccarello, F.
Observations show that during solar flares radiation can be emitted across the entire electromagnetic spectrum, spanning from gamma rays to radio waves. These emissions, related to the conversion of magnetic energy into other forms of energy (kinetic, thermal, waves) through magnetic reconnection, are due to different physical processes that can o…
Broadband X-ray study of the galactic black hole binary 4U 1630-47 with Suzaku
Done, C.; Hori, T.; Shidatsu, M. +4 more
We present the results from our Suzaku observations of the Galactic black hole binary 4U 1630-47. 4U 1630-47 was observed in the very high state (VHS) during the 2012 September-October outburst. The inner disk appears slightly truncated by comparison with a previous high/soft state (HSS) of this source, even by taking into account energetic coupli…
Effect of the meridional velocity gradient on the anisotropy of turbulence in the solar wind
Erofeev, D. V.
In this paper, the heliolatitude dependence of the anisotropy of hourly interplanetary magnetic field fluctuations under conditions characteristic of low solar activity is studied. Measurements carried out by the Ulysses spacecraft in 1992–1994 and 1995–1997 are analyzed. It is found that the minimum fluctuation variance axis has a significant til…
First analysis of eight Algol-type binaries: EI Aur, XY Dra, BP Dra, DD Her, VX Lac, WX Lib, RZ Lyn, and TY Tri
Zasche, P.
The available photometry from the online databases were used for the first light curve analysis of eight eclipsing binary systems EI Aur, XY Dra, BP Dra, DD Her, VX Lac, WX Lib, RZ Lyn, and TY Tri. All these stars are of Algol-type, having the detached components and the orbital periods from 0.92 to 6.8 days. For the systems EI Aur and BP Dra the …
Some properties of field-aligned electron events in high-altitude polar regions
Zhang, ZiYing; Shi, JianKui; Zhou, MingQuan +2 more
Using data from the Cluster spacecraft from January 2003 to December 2004, we perform a statistical study on some properties of the field-aligned electron (FAE) events and interplanetary magnetic field (IMF) By dependence of FAE events with different durations in high-altitude polar regions. A total of 1335 FAE events were observed by the C3 space…
Milky Way mapper: 6 ways the Gaia spacecraft will change astronomy
Castelvecchi, Davide
European mission will shed light on hidden asteroids, the Universe’s expansion and exoplanets.
Dusty Quasars at High Redshifts
Weedman, Daniel; Sargsyan, Lusine
A population of quasars at z ∼ 2 is determined based on dust luminosities νL ν (7.8 µm) that includes unobscured, partially obscured, and obscured quasars. Quasars are classified by the ratio νL ν (0.25 µm)/νL ν (7.8 µm) = UV/IR, assumed to measure obscuration of UV luminosity by the dust that …
Hubble imaging of V1331 Cygni: proper motion study of its circumstellar structures
Stecklum, B.; Linz, Hendrik; Choudhary, A.
Aims: The young star V1331 Cyg received previous attention because it is surrounded by an optical, arc-like reflection nebula. V1331 Cyg is commonly considered to be a candidate for an object that has undergone an FU-Ori (FUOR) outbreak in the past. This in turn could lead to a time-varying appearance of the dusty arcs that may be revealed by…
