Long-term Spectroscopic Monitoring of LBVs and LBV Candidates
A. Lobel, J. H. Groh, K. Torres +1
We present results of a long-term spectroscopic monitoring program (since mid 2009) of Luminous Blue Variables with the new HERMES echelle spectrograph on the 1.2 m Mercator telesc…
The widespread occurence of water vapor in the circumstellar envelopes of carbon-rich AGB stars: first results from a survey with Herschel/HIFI

MESS (Mass-loss of Evolved StarS), a Herschel Key Program
M. A. T. Groenewegen, C. Waelkens, M. J. Barlow +39
MESS (Mass-loss of Evolved StarS) is a Guaranteed Time Key Program that uses the PACS and SPIRE instruments on board the Herschel Space Observatory to observe a representative samp…
Herschel/HIFI observations of IRC+10216: water vapor in the inner envelope of a carbon-rich AGB star
David A. Neufeld, Eduardo González-Alfonso, Gary J. Melnick +6
We report the results of observations of ten rotational transitions of water vapor toward the carbon-rich AGB (asymptotic giant branch) star IRC+10216 (CW Leonis), carried out with…
The 9.7 and 18 um silicate absorption profiles towards diffuse and molecular cloud lines-of-sight
J. M. van Breemen, M. Min, J. E. Chiar +8
Studying the composition of dust in the interstellar medium (ISM) is crucial in understanding the cycle of dust in our galaxy. The mid-infrared spectral signature of amorphous sili…
The Potential of the Timing Method to Detect Evolved Planetary Systems
Roberto Silvotti, Robert Szabo, Pieter Degroote +2
The timing method, using either stellar pulsations or eclipse timing of close binaries as a clock, is proving to be an efficient way to detect planets around stars that have evolve…
Zeta functions and Bernstein-Sato polynomials for ideals in dimension two
Bart Bories
For a nonzero ideal I of C[x_1,...,x_n], with 0 in supp I, a generalization of a conjecture of Igusa - Denef - Loeser predicts that every pole of its topological zeta function is a…
One-cohomology and the uniqueness of the group measure space decomposition of a II_1 factor
Stefaan Vaes
We provide a unified and self-contained treatment of several of the recent uniqueness theorems for the group measure space decomposition of a II_1 factor. We single out a large cla…
Igusa's p-adic local zeta function associated to a polynomial mapping and a polynomial integration measure
Bart Bories
For p prime, we give an explicit formula for Igusa's local zeta function associated to a polynomial mapping f=(f_1,...,f_t): Q_p^n -> Q_p^t, with f_1,...,f_t in Z_p[x_1,...,x_n], a…
Motivic zeta functions for degenerations of abelian varieties and Calabi-Yau varieties
Lars Halvard Halle, Johannes Nicaise
This is a survey on motivic zeta functions associated to abelian varieties and Calabi-Yau varieties over a discretely valued field. We explain how they are related to Denef and Loe…
Higher-dimensional Rotating Charged Black Holes
Marco M. Caldarelli, Roberto Emparan, Bert Van Pol
Using the blackfold approach, we study new classes of higher-dimensional rotating black holes with electric charges and string dipoles, in theories of gravity coupled to a 2-form o…
The Hyper-MUCHFUSS project: probing the Galactic halo with sdB stars
A. Tillich, U. Heber, S. Geier +7
High-velocity stars in the Galactic halo, e.g. the so-called hyper-velocity stars (HVS), are important tracers of the properties of the dark matter halo, in particular its mass. Ba…
Experimental evidence on the Altshuler-Aronov-Spivak interference of the topological surface states in the exfoliated Bi2Te3 nanoflakes
Yuyuan Qin, Zhaoguo Li, Fengqi Song +10
Here we demonstrate the Altshuler-Aronov-Spivak (AAS) interference of the topological surface states on the exfoliated Bi2Te3 microflakes by a flux period of h/2e in their magnetor…
Chronology protection and the stringy exclusion principle
Joris Raeymaekers, Dieter Van den Bleeken, Bert Vercnocke
We construct a family of supersymmetric solutions to AdS supergravity in three dimensions, that correspond to type IIB seven branes wrapped on an internal S3xT4. These solutions ar…
