Near-infrared counterparts to the Galactic Bulge Survey X-ray source population

S. Greiss, D. Steeghs, P. G. Jonker +6

We report on the near-infrared matches, drawn from three surveys, to the 1640 unique X-ray sources detected by Chandra in the Galactic Bulge Survey (GBS). This survey targets faint…

A physical model for the flickering variability in cataclysmic variables

Simone Scaringi

Aperiodic broad-band variability (also known as flickering) is observed throughout all types of accreting compact objects. Many statistical properties of this variability can be na…

Relativistic AGN jets II. Jet properties and mixing effects for episodic jet activity

Sander Walg, Abraham Achterberg, Sera Markoff +2

Various radio galaxies show signs of having gone through episodic jet outbursts in the past. An example is the class of double-double radio galaxies (DDRGs). However, to follow the…

The VMC Survey - X. Cepheids, RR Lyrae stars and binaries as probes of the Magellanic System's structure

M. I. Moretti, G. Clementini, T. Muraveva +12

The VMC survey is obtaining multi-epoch photometry in the Ks band of the Magellanic System down to a limiting magnitude of Ks ~ 19.3 for individual epoch data. The observations are…

Herschel SPIRE and PACS observations of the red supergiant VY CMa: analysis of the molecular line spectra

Mikako Matsuura, J. A. Yates, M. J. Barlow +10

We present an analysis of the far-infrared and submillimetre molecular emission line spectrum of the luminous M-supergiant VY CMa, observed with the SPIRE and PACS spectrometers ab…

Kepler observations of the eclipsing cataclysmic variable KIS J192748.53+444724.5

S. Scaringi, P. J. Groot, M. Still

We present results from long cadence Kepler observations covering 97.6 days of the newly discovered eclipsing cataclysmic variable KIS J192748.53+444724.5/KIC 8625249. We detect de…

ALMA observations of the Red Rectangle, a preliminary analysis

V. Bujarrabal, A. Castro-Carrizo, J. Alcolea +5

We aim to study equatorial disks in rotation and axial outflows in post-AGB objects, as to disclose the formation and shaping mechanisms in planetary nebulae. So far, both disks an…

Diffuse interstellar bands in M33

Keith T. Smith, Martin A. Cordiner, Christopher J. Evans +2

We present the first sample of diffuse interstellar bands (DIBs) in the nearby galaxy M33. Studying DIBs in other galaxies allows the behaviour of the carriers to be examined under…

Extended rotating disks around post-AGB stars

V. Bujarrabal, J. Alcolea, H. Van Winckel +2

There is a group of binary post-AGB stars that show a conspicuous NIR excess, usually assumed to arise from hot dust in very compact possibly rotating disks. These stars are surrou…

GASPS - a Herschel survey of gas and dust in Protoplanetary Disks: Summary and Initial Statistics

W. R. F. Dent, W. F. Thi, I. Kamp +47

GASPS is a far-infrared line and continuum survey of protoplanetary and young debris disks using PACS on the Herschel Space Observatory. The survey includes [OI] at 63 microns, as…

Herschel/HIFI search for H2-17O and H2-18O in IRC+10216: constraints on models for the origin of water vapor

David A. Neufeld, Volker Tolls, Marcelino Agúndez +7

We report the results of a sensitive search for the minor isotopologues of water, H2-17O and H2-18O, toward the carbon-rich AGB star IRC+10216 (a.k.a. CW Leonis) using the HIFI ins…

Discovery of Fourier-dependent time lags in cataclysmic variables

S. Scaringi, E. Koerding, P. J. Groot +5

We report the first study of Fourier-frequency-dependent coherence and phase/time lags at optical wavelengths of cataclysmic variables (MV Lyr and LU Cam) displaying typical flicke…
