High resolution spectroscopy of Ne II emission from young stellar objects
G. G. Sacco, E. Flaccomio, I. Pascucci +6
Constraining the spatial and thermal structure of the gaseous component of circumstellar disks is crucial to understand star and planet formation. Models predict that the [Ne II] l…
Warm gas at 50 AU in the disk around Herbig Be star HD 100546
M. Goto, G. van der Plas, M. van den Ancker +6
The disk atmosphere is one of the fundamental elements of theoretical models of a protoplanetary disk. However, the direct observation of the warm gas (>> 100 K) at large radius of…
Finding proto-spectroscopic binaries: Precise multi-epoch radial velocities of 7 protostars in rho-Ophiuchus
P. Viana Almeida, C. Melo, N. C. Santos +3
The formation of spectroscopic binaries (SB) may be a natural byproduct of star formation. The early dynamical evolution of multiple stellar systems after the initial fragmentation…
Star Formation and AGN activity in Galaxies classified using the 1.6 μm Bump and PAH features at

The narrow, inner CO ring around the magnetic Herbig Ae star, HD 101412
C. R. Cowley, S. Hubrig, F. Castelli +1
We describe and model emission lines in the first overtone band of CO in the magnetic Herbig Ae star HD 101412. High-resolution CRIRES spectra reveal unusually sharp features which…
Modeling the Asymmetric Wind of Massive LBV Binary MWC 314
A. Lobel, J. Groh, K. Torres Dozinel +13
Spectroscopic monitoring with Mercator-HERMES over the past two years reveals that MWC 314 is a massive binary system composed of an early B-type primary LBV star and a less-lumino…
Shape modeling technique KOALA validated by ESA Rosetta at (21) Lutetia
B. Carry, M. Kaasalainen, W. J. Merline +12
We present a comparison of our results from ground-based observations of asteroid (21) Lutetia with imaging data acquired during the flyby of the asteroid by the ESA Rosetta missio…
AMBER/VLTI observations of 5 giant stars
F. Cusano, C. Paladini, A. Richichi +6
While the search for exoplanets around main sequence stars more massive than the Sun have found relatively few such objects, surveys performed around giant stars have led to the di…
Spectroscopy of the spatially-extended Lya emission around a QSO at z=6.4
Tomotsugu Goto, Yousuke Utsumi, Jeremy R. Walsh +3
We have taken a deep, moderate-resolution Keck/Deimos spectra of QSO, CFHQS2329, at z=6.4. At the wavelength of Lya, the spectrum shows a spatially-extended component, which is sig…
Environmental effects in the interaction and merging of galaxies in zCOSMOS
P. Kampczyk, S. J. Lilly, L. de Ravel +56
(Abridged) We analyze the environments and galactic properties (morphologies and star-formation histories) of a sample of 153 close kinematic pairs in the redshift range 0.2 < z <…
A Magellan-IMACS-IFU Search for Dynamical Drivers of Nuclear Activity. I. Reduction Pipeline and Galaxy Catalog
Paul Westoby, Carole Mundell, Neil Nagar +5
Using the Inamori Magellan Areal Camera and Spectrograph (IMACS) integral-field unit (IFU) on the 6.5m Magellan telescope, we have designed the first statistically significant inve…
The specific frequencies of ultra-compact dwarf galaxies
Steffen Mieske, Michael Hilker, Ingo Misgeld
We aim at quantifying the specific frequency of UCDs in a range of environments and at relating this to the frequency of globular clusters (GCs) and potential progenitor dwarf gala…
The Cosmic Web and galaxy evolution around the most luminous X-ray cluster: RXJ1347.5-1145
M. Verdugo, M. Lerchster, H. Boehringer +5
In this paper we study the large scale structures and their galaxy content around the most X-ray luminous cluster known, RX J1347.5-1145 at z=0.45. We make use of ugriz CFHT MEGACA…
The ongoing assembly of a central cluster galaxy: Phase-space substructures in the halo of M87
Aaron J. Romanowsky, Jay Strader, Jean P. Brodie +5
The halos of galaxies preserve unique records of their formation histories. We carry out the first combined observational and theoretical study of phase-space halo substructure in…
Strengthening the Open Cluster Distance Scale via VVV Photometry
Daniel J. Majaess, David G. Turner, C. Moni Bidin +14
Approximately 14% of known Galactic open clusters possess absolute errors 20% as evaluated from n>3 independent distance estimates, and the statistics for age estimates are markedl…
The Atlas3D Project -- XI. Dense molecular gas properties of CO-luminous early-type galaxies
Alison Crocker, Melanie Krips, Martin Bureau +24
Surveying eighteen 12CO-bright galaxies from the ATLAS3D early-type galaxy sample with the Institut de Radio Astronomie Millimétrique (IRAM) 30m telescope, we detect 13CO(1-0) and…
More on the structure of tidal tails
Andreas H. W. Kuepper, Richard R. Lane, Douglas C. Heggie
We investigate the epicyclic motion of stars escaping from star clusters. Using streaklines, we visualise the path of escaping stars and show how epicyclic motion leads to over- an…
