Observations of a rotating macrospicule associated with an X-ray jet
Solanki, S. K.; Inhester, B.; Curdt, W. +2 more
Aims: We attempt to understand the driving mechanism of a macrospicule and its relationship with a coronal jet.
Methods: We study the dynamics of a macrospicule and an associated coronal jet captured by multi-spacecraft observations. Doppler velocities in both the macrospicule and the coronal jet are determined by EIS and SUMER spectra. …
Star formation and dust extinction properties of local galaxies from the AKARI-GALEX all-sky surveys . First results from the most secure multiband sample from the far-ultraviolet to the far-infrared
Buat, V.; Burgarella, D.; Takeuchi, T. T. +5 more
Aims: We explore spectral energy distributions (SEDs), star formation (SF), and dust extinction properties of galaxies in the Local Universe.
Methods: The AKARI all-sky survey provided the first bright point source catalog detected at 90 µm. Beginning with this catalog, we selected galaxies by matching the AKARI sources with those …
The baryonic content and Tully-Fisher relation at z ~ 0.6
Yang, Y.; Flores, H.; Hammer, F. +3 more
Context. Using the multi-integral-field spectrograph GIRAFFE at VLT, we previsouly derived the stellar-mass Tully-Fisher Relation (smTFR) at z ~ 0.6 for a representative sample of 63 emission-line galaxies. We found that the distant relation is systematically offset by roughly a factor of two toward lower masses from the local relation.
Aims:…
Transiting exoplanets from the CoRoT space mission. X. CoRoT-10b: a giant planet in a 13.24 day eccentric orbit
Mazeh, T.; Aigrain, S.; Alonso, R. +47 more
Context. The space telescope CoRoT searches for transiting extrasolar planets by continuously monitoring the optical flux of thousands of stars in several fields of view.
Aims: We report the discovery of CoRoT-10b, a giant planet on a highly eccentric orbit (e = 0.53 ± 0.04) revolving in 13.24 days around a faint (V = 15.22) metal-rich K1V st…
Transiting exoplanets from the CoRoT space mission. XIV. CoRoT-11b: a transiting massive ``hot-Jupiter'' in a prograde orbit around a rapidly rotating F-type star
Mazeh, T.; Aigrain, S.; Alonso, R. +52 more
The CoRoT exoplanet science team announces the discovery of CoRoT-11b, a fairly massive hot-Jupiter transiting a V = 12.9 mag F6 dwarf star (M_* = 1.27±0.05 M⊙, R_* = 1.37±0.03 R⊙, Teff = 6440±120 K), with an orbital period of P = 2.994329±0.000011 days and semi-major axis a = 0.0436±0.005 AU. The detection of part…
High-resolution imaging of Galactic massive stars with AstraLux. I. 138 fields with δ > - 25°
Maíz Apellániz, J.
Context. Massive stars have high-multiplicity fractions, and many of them have still undetected components, thus hampering the study of their properties.
Aims: I study a sample of massive stars with high angular resolution to better characterize their multiplicity.
Methods: I observed 138 fields that include at least one massive star wit…
SPIRE spectroscopy of the prototypical Orion Bar photodissociation region
Miville-Deschênes, M. -A.; Boulanger, F.; Abergel, A. +42 more
Aims: We present observations of the Orion Bar photodissociation region (PDR) obtained with the SPIRE instrument on-board Herschel.
Methods: We obtained SPIRE Fourier-transform spectrometer (FTS) sparse sampled maps of the Orion bar.
Results: The FTS wavelength coverage and sensitivity allow us to detect a wealth of rotational lines…
Nitrogen hydrides in interstellar gas. Herschel/HIFI observations towards G10.6-0.4 (W31C)
Perault, M.; Boulanger, F.; Falgarone, E. +49 more
The HIFI instrument on board the Herschel Space Observatory has been used to observe interstellar nitrogen hydrides along the sight-line towards G10.6-0.4 in order to improve our understanding of the interstellar chemistry of nitrogen. We report observations of absorption in NH N = 1 ≤ftarrow 0, J = 2 ≤ftarrow 1 and ortho-NH2 11,1<…
First results of Herschel-PACS observations of Neptune
Blommaert, J. A. D. L.; Lara, L. M.; Küppers, M. +51 more
We report on the initial analysis of a Herschel-PACS full range spectrum of Neptune, covering the 51-220 µm range with a mean resolving power of ~3000, and complemented by a dedicated observation of CH4 at 120 µm. Numerous spectral features due to HD (R(0) and R(1)), H2O, CH4, and CO are present, but so…
The CHESS spectral survey of star forming regions: Peering into the protostellar shock L1157-B1. II. Shock dynamics
Falgarone, E.; Maret, S.; Henning, T. +74 more
Context. The outflow driven by the low-mass class 0 protostar L1157 is the prototype of the so-called chemically active outflows. The bright bowshock B1 in the southern outflow lobe is a privileged testbed of magneto-hydrodynamical (MHD) shock models, for which dynamical and chemical processes are strongly interdependent.
Aims: We present the…
