Tie Liu, Qizhou Zhang, Kee-Tae Kim +37
We are performing a series of observations with ground-based telescopes toward Planck Galactic cold clumps (PGCCs) in the Orionis complex in order to systematically investigate…
Absence of Significant Cool Disks in Young Stellar Objects Exhibiting Repetitive Optical Outbursts
Hauyu Baobab Liu, Roberto Galván-Madrid, Eduard I. Vorobyov +10
We report Submillimeter Array (SMA) 1.3 mm high angular resolution observations towards the four EXor type outbursting young stellar objects (YSOs) VY Tau, V1118 Ori, V1143 Ori, an…
A catalog of early-type stars toward the Galactic center
Preben Grosbøl
It is still unclear whether the Sagittarius spiral arm is a major spiral arm in the Galaxy or whether it just outlines a region of enhanced star formation because of the local comp…
Polarimetry of the superluminous supernova LSQ14mo: no evidence for significant deviations from spherical symmetry
Giorgos Leloudas, Ferdinando Patat, Justyn R. Maund +10
We present the first polarimetric observations of a Type I superluminous supernova (SLSN). LSQ14mo was observed with VLT/FORS2 at five different epochs in the V band, with the obse…
Orbits in the T Tauri triple system observed with SPHERE
R. Köhler, M. Kasper, T. M. Herbst +2
We present new astrometric measurements of the components in the T Tauri system, and derive new orbits and masses. T Tauri was observed during the science verification time of the…
A multi-wavelength analysis for interferometric (sub-)mm observations of protoplanetary disks: radial constraints on the dust properties and the disk structure
M. Tazzari, L. Testi, B. Ercolano +20
Theoretical models of grain growth predict dust properties to change as a function of protoplanetary disk radius, mass, age and other physical conditions. We lay down the methodolo…
Apodization in high-contrast long-slit spectroscopy. II. Concept validation and first on-sky results with VLT/SPHERE
A. Vigan, M. N'Diaye, K. Dohlen +20
Spectral characterization of young, giant exoplanets detected by direct imaging is one of the tasks of the new generation of high-contrast imagers. For this purpose, the VLT/SPHERE…
ALFA: an automated line fitting algorithm
Roger Wesson
I present the Automated Line Fitting Algorithm, ALFA, a new code which can fit emission line spectra of arbitrary wavelength coverage and resolution, fully automatically. In contra…
The XXL Survey VII: A supercluster of galaxies at z=0.43
E. Pompei, C. Adami, D. Eckert +15
The XXL Survey is the largest homogeneous and contiguous survey carried out with XMM-Newton. Covering an area of 50 square degrees distributed over two fields, it primarily investi…
A continuum from clear to cloudy hot-Jupiter exoplanets without primordial water depletion
David K. Sing, Jonathan J. Fortney, Nikolay Nikolov +18
Thousands of transiting exoplanets have been discovered, but spectral analysis of their atmospheres has so far been dominated by a small number of exoplanets and data spanning rela…
The XXL Survey: I. Scientific motivations - XMM-Newton observing plan - Follow-up observations and simulation programme
M. Pierre, F. Pacaud, C. Adami +89
We present the XXL Survey, the largest XMM programme totaling some 6.9 Ms to date and involving an international consortium of roughly 100 members. The XXL Survey covers two extrag…
The XXL Survey. II. The bright cluster sample: catalogue and luminosity function
F. Pacaud, N. Clerc, P. A. Giles +40
Context. The XXL Survey is the largest survey carried out by the XMM-Newton satellite and covers a total area of 50 square degrees distributed over two fields. It primarily aims at…
The frequency of accretion disks around single stars: Chamaeleon I
Sebastian Daemgen, R. Elliot Meyer, Ray Jayawardhana +1
It is well known that stellar companions can influence the evolution of a protoplanetary disk. Nevertheless, previous disk surveys did not - and could not - consistently exclude bi…
The first Galaxy scale hunt for the youngest high-mass protostars
T. Csengeri, S. Bontemps, F. Wyrowski +17
The origin of massive stars is a fundamental open issue in modern astrophysics. Pre-ALMA interferometric studies reveal precursors to early B to late O type stars with collapsing e…
