Deriving Metallicities from Calcium Triplet Spectroscopy in combination with Near Infrared Photometry
F. Mauro, C. Moni Bidin, D. Geisler +7
Context. [...] One of the most efficient methods is the measurement of the equivalent width (EW) of the Calcium II Triplet (CaT), corrected for the luminosity and temperature effec…
Investigating potential planetary nebula/cluster pairs
Christian Moni Bidin, Daniel Majaess, Charles Bonatto +10
Fundamental parameters characterizing the end-state of intermediate-mass stars may be constrained by discovering planetary nebulae (PNe) in open clusters (OCs). Cluster membership…
Upgrading electron temperature and electron density diagnostic diagrams of forbidden line emission
Bastian Proxauf, Silvia Oettl, Stefan Kimeswenger
Diagnostic diagrams of forbidden lines have been a useful tool for observers in astrophysics for many decades now. They are used to obtain information on the basic physical propert…
Spectral results for the dominating induced matching problem
Domingos M. Cardoso, Enide A. Martins, Luís Medina +1
A matching M is a dominating induced matching of a graph, if every edge of the graph is either in or has a common end-vertex with exactly one edge in . The concept of comple…
Anchors for the Cosmic Distance Scale: the Cepheids U Sgr, CF Cas and CEab Cas
D. Majaess, G. Carraro, C. Moni Bidin +11
New and existing X-ray, UBVJHKsW(1-4), and spectroscopic observations were analyzed to constrain fundamental parameters for M25, NGC 7790, and dust along their sight-lines. The sta…
Topological Conjugacy of Real Projective Flows
Victor Ayala, Christoph Kawan
In this paper we prove the following topological classification result for flows on real projective space induced by linear flows on Euclidean space: Two flows on the projective sp…
An advanced scattered moonlight model for Cerro Paranal
Amy Jones, Stefan Noll, Wolfgang Kausch +2
The largest natural source of light at night is the Moon, and it is the major contributor to the astronomical sky background. Being able to accurately predict the sky background, i…
Ruprecht 106: the first single population Globular Cluster?
S. Villanova, D. Geisler, G. Carraro +2
All old Galactic Globular Clusters studied in detail to date host at least two generations of stars, where the second is formed from gas polluted by processed material produced by…
New visual companions of solar-type stars within 25 pc
R. Chini, K. Fuhrmann, A. Barr Domínguez +3
We report the discovery of faint common-proper-motion companions to the nearby southern solar-type stars HD43162, HD67199, HD114837, HD114853, HD129502, HD165185, HD197214, and HD2…
The Berlin Exoplanet Search Telescope II. Catalog of Variable Stars. I. Characterization of Three Southern Target Fields
T. Fruth, J. Cabrera, R. Chini +11
A photometric survey of three Southern target fields with BEST II yielded the detection of 2,406 previously unknown variable stars and an additional 617 stars with suspected variab…
Hubble Space Telescope and Ground-Based Observations of V455 Andromedae Post-Outburst
Paula Szkody, Anjum S. Mukadam, Boris T. Gaensicke +8
Hubble Space Telescope spectra obtained in 2010 and 2011, three and four years after the large amplitude dwarf nova outburst of V455 And, were combined with optical photometry and…
Modelling photometric reverberation data -- a disk-like broad-line region and a potentially larger black hole mass for 3C120
F. Pozo Nuñez, M. Haas, M. Ramolla +7
We consider photometric reverberation mapping, where the nuclear continuum variations are monitored via a broad-band filter and the echo of emission line clouds of the broad line r…
739 observed NEAs and new 2-4m survey statistics within the EURONEAR network
O. Vaduvescu, M. Birlan, A. Tudorica +36
We report follow-up observations of 477 program Near-Earth Asteroids (NEAs) using nine telescopes of the EURONEAR network having apertures between 0.3 and 4.2 m. Adding these NEAs…
RR Lyrae variables: visual and infrared luminosities, intrinsic colours, and kinematics
A. K. Dambis, L. N. Berdnikov, A. Y. Kniazev +4
We use UCAC4 proper motions and WISE W1-band apparent magnitudes intensity-mean for almost 400 field RR Lyrae variables to determine the parameters of the velocity distribution of…
Curvature of fluctuation geometry and its implications on Riemannian fluctuation theory
L. Velazquez
Fluctuation geometry was recently proposed as a counterpart approach of Riemannian geometry of inference theory. This theory describes the geometric features of the statistical man…
Improving the efficiency of Monte Carlo simulations of systems that undergo temperature-driven phase transitions
L. Velazquez, J. C. Castro-Palacio
Recently, Velazquez and Curilef have proposed a methodology to extend Monte Carlo algorithms based on canonical ensemble, which is aimed to overcome slow sampling problems associat…
Spectroscopy of blue horizontal branch stars in NGC 6656 (M22)
C. Salgado, C. Moni Bidin, S. Villanova +2
Recent investigations revealed very peculiar properties of blue horizontal branch (HB) stars in ωCentauri, which show anomalously low surface gravity and mass compared to other clu…
CEN34 -- High-Mass YSO in M17 or Background Post-AGB Star?
Zhiwei Chen, Dieter Nuernberger, Rolf Chini +3
We investigate the proposed high-mass young stellar object (YSO) candidate CEN34, thought to be associated with the star forming region M17. Its optical to near-infrared (550-2500…
Electronic transport of folded graphene nanoribbons
Jhon W. González, Mónica Pacheco, Pedro Orellana +2
We investigate the electronic transport properties of a folded graphene nanoribbon with monolayer nanoribbon contacts. We consider two possible foldings: either the nanoribbon can…
