Bernoulli trials of fixed parity, random and randomly oriented graphs

Christos Pelekis

Suppose you can color \emph{biased} coins with colors, all coins having the same bias. It is forbidden to color both sides of a coin with the same color, but all other colo…

Extensive study of HD 25558, a long-period double-lined binary with two SPB components

Á. Sódor, P. De Cat, D. J. Wright +33

We carried out an extensive observational study of the Slowly Pulsating B (SPB) star, HD 25558. The ~2000 spectra obtained at different observatories, the ground-based and MOST sat…

Negation in the Head of CP-logic Rules

Joost Vennekens

CP-logic is a probabilistic extension of the logic FO(ID). Unlike ASP, both of these logics adhere to a Tarskian informal semantics, in which interpretations represent objective st…

BPS domain walls from backreacted orientifolds

Johan Blåbäck, Bert Janssen, Thomas Van Riet +1

Compactifications with D-brane and orientifold sources lead to standard gauged supergravity theories if the sources are smeared over the internal directions. It is therefore of int…

Can the magnetic field in the Orion arm inhibit the growth of instabilities in the bow shock of Betelgeuse?

Allard Jan van Marle, Leen Decin, Zakaria Meliani

Many evolved stars travel through space at supersonic velocities, which leads to the formation of bow shocks ahead of the star where the stellar wind collides with the interstellar…

Electrostatic plasma instabilities driven by neutral gas flows in the solar chromosphere

G. Gogoberidze, Y. Voitenko, S. Poedts +1

We investigate electrostatic plasma instabilities of Farley-Buneman (FB) type driven by quasi-stationary neutral gas flows in the solar chromosphere. The role of these instabilitie…

Nielsen zeta functions on infra-nilmanifolds up to dimension three

Gert-Jan Dugardein

In this paper, we will list all possible self-maps on infra-nilmanifolds up to dimension three and we will give the Nielsen zeta function for any of those maps.

The atmospheric chemistry of the warm Neptune GJ 3470b: influence of metallicity and temperature on the CH4/CO ratio

Olivia Venot, Marcelino Agundez, Franck Selsis +2

Current observation techniques are able to probe the atmosphere of some giant exoplanets and get some clues about their atmospheric composition. However, the chemical compositions…

On kernel smoothing for extremal quantile regression

Abdelaati Daouia, Laurent Gardes, Stéphane Girard

Nonparametric regression quantiles obtained by inverting a kernel estimator of the conditional distribution of the response are long established in statistics. Attention has been,…

The behavior of transverse waves in nonuniform solar flux tubes. II. Implications for coronal loop seismology

Roberto Soler, Marcel Goossens, Jaume Terradas +1

Seismology of coronal loops using observations of damped transverse oscillations in combination with results from theoretical models is a tool to indirectly infer physical paramete…

What asteroseismology can do for exoplanets: Kepler-410A b is a Small Neptune around a bright star, in an eccentric orbit consistent with low obliquity

Vincent Van Eylen, Mikkel N. Lund, Victor Silva Aguirre +12

We confirm the Kepler planet candidate Kepler-410b (KOI-42b) as a Neptune sized exoplanet on a 17.8 day, eccentric orbit around the bright (Kp = 9.4) star Kepler-410A. This is the…

Pulsating red giant stars in eccentric binary systems discovered from Kepler space-based photometry

P. G. Beck, K. Hambleton, J. Vos +30

The unparalleled photometric data obtained by NASA's Kepler space telescope led to an improved understanding of red giant stars and binary stars. Seismology allows us to constrain…

Zero distribution of complex orthogonal polynomials with respect to exponential weights

Daan Huybrechs, Arno Kuijlaars, Nele Lejon

We study the limiting zero distribution of orthogonal polynomials with respect to some particular exponential weights exp(-nV(z)) along contours in the complex plane. We are especi…
