C - looking for the bucky-ball in interstellar space
G. A. Galazutdinov, V. V. Shimansky, A. Bondar +2
The laboratory gas phase spectrum recently published by Campbell et al. has reinvigorated attempts to confirm the presence of the C cation in the interstellar medium, thor…
(sub)Millimeter Emission Lines of Molecules in Born-again Stars
D. Tafoya, J. A. Toalá, W. H. T. Vlemmings +7
The detection and study of molecular gas in born-again stars would be of great importance to understand their composition and chemical evolution. In addition, the molecular emissio…
Galactic structure in the outer disk: the field in the line of sight to the intermediate-age open cluster Tombaugh 1
Giovanni Carraro, Joao Victor Sales Silva, Christian Moni Bidin +1
We employ optical photometry and high-resolution spectroscopy to study a field toward the open cluster Tombaugh 1, where we identify a complex population mixture, that we describe…
Young stars in the periphery of the Large Magellanic Cloud
C. Moni Bidin, D. I. Casetti-Dinescu, T. M. Girard +5
Despite their close proximity, the complex interplay between the two Magellanic Clouds, the Milky Way, and the resulting tidal features, is still poorly understood. Recent studies…
ALMA observations of the nearby AGB star L2 Puppis - I. Mass of the central star and detection of a candidate planet
P. Kervella, W. Homan, A. M. S. Richards +4
Six billion years from now, while evolving on the asymptotic giant branch (AGB), the Sun will metamorphose from a red giant into a beautiful planetary nebula. This spectacular evol…
Clumpy dust clouds and extended atmosphere of the AGB star W Hya revealed with VLT/SPHERE-ZIMPOL and VLTI/AMBER II. Time variations between pre-maximum and minimum light
Keiichi Ohnaka, Gerd Weigelt, Karl-Heinz Hofmann
Our recent visible polarimetric images of the well-studied AGB star W Hya taken at pre-maximum light (phase 0.92) with VLT/SPHERE-ZIMPOL have revealed clumpy dust clouds close to t…
Fano-Andreev effect in T-shape double-quantum-dot in the Kondo regime
A. M. Calle, M. Pacheco, G. B. Martins +3
In the present work, we investigate the electronic transport through a T-shape double quantum dot system coupled to two normal leads and to one superconducting lead. We explore the…
VLTI-AMBER velocity-resolved aperture-synthesis imaging of Eta Carinae with a spectral resolution of 12000. Studies of the primary star wind and innermost wind-wind collision
G. Weigelt, K. -H. Hofmann, D. Schertl +26
Context. The mass loss from massive stars is not understood well. Eta Car is a unique object for studying the massive stellar wind during the LBV phase. It is also an eccentric bin…
Multi-wavelength observations of IGR J17544-2619 from quiescence to outburst
E. Bozzo, V. Bhalerao, P. Pradhan +12
In this paper we report on a long multi-wavelength observational campaign of the supergiant fast X-ray transient prototype IGR J17544-2619. A 150 ks-long observation was carried ou…
Thermodynamics of gravitational clustering phenomena: -body self-gravitating gas on the sphere
F. Tello-Ortiz, L. Velazquez
This work is devoted to the thermodynamics of gravitational clustering, a collective phenomenon with a great relevance in the -body cosmological problem. We study a classical se…
A spectroscopic study of the Globular Cluster M28 (NGC~6626)
S. Villanova, C. Moni Bidin, F. Mauro +2
We present the abundance analysis for a sample of 17 red giant branch stars in the metal-poor globular cluster M28 based on high resolution spectra. This is the first extensive spe…
A Lie theoretical construction of a Landau-Ginzburg model without projective mirrors
Edoardo Ballico, Severin Barmeier, Elizabeth Gasparim +2
We describe the Fukaya-Seidel category of a Landau-Ginzburg model LG(2) for the semisimple adjoint orbit of sl(2,C). We prove that this category is equivalent to a full triangulate…
The power of a control qubit in weak measurements
Raul Coto, Víctor Montenegro, Vitalie Eremeev +2
In the late 80s, a curious effect suggested by Aharanov, Albert and Vaidman opened up new vistas regarding quantum measurements on weakly coupled systems. There, a combination of a…
Near-Infrared Photometry of Globular Clusters Towards the Galactic Bulge: Observations and Photometric Metallicity Indicators
Roger E. Cohen, Christian Moni Bidin, Francesco Mauro +2
We present wide field JHKs photometry of 16 Galactic globular clusters located towards the Galactic bulge, calibrated on the 2MASS photometric system. Differential reddening correc…
Ultra-deep GEMINI near-infrared observations of the bulge globular cluster NGC 6624
S. Saracino, E. Dalessandro, F. R. Ferraro +8
We used ultra-deep and images secured with the near-infrared GSAOI camera assisted by the multi-conjugate adaptive optics system GeMS at the GEMINI South Telescope in Chi…
New Suns in the Cosmos II: Differential rotation in Kepler Sun-like stars
M. L. Das Chagas, J. P. Bravo, A. D. Costa +9
The present study reports the discovery of Sun-like stars, namely main-sequence stars with , and rotation periods similar to solar values, presentin…
Reconstruction of an effective magnon mean free path distribution from spin Seebeck measurements in thin films
E. Chavez-Angel, R. A. Zarate, S. Fuentes +3
A thorough understanding of the mean-free-path (MFP) distribution of the energy carriers is crucial to engineer and tune the transport properties of materials. In this context, a s…
