The crucial role of surface magnetic fields for the solar dynamo

Kavli Affiliate: Robert Cameron | First 5 Authors: Robert Cameron, Manfred Schüssler, , , | Summary: Sunspots and the plethora of other phenomena occuring in the course of the 11-year cycle of solar activity are a consequence of the emergence of magnetic flux at the solar surface. The observed orientations of bipolar sunspot groups imply […]

Spitzer Survey of Stellar Structure in Galaxies (S$^4$G). The Pipeline 4: Multi-component decomposition strategies and data release

Kavli Affiliate: Luis Ho | First 5 Authors: Heikki Salo, Eija Laurikainen, Jarkko Laine, Sebastien Comerón, Dimitri A. Gadotti | Summary: The Spitzer Survey of Stellar Structure in Galaxies (S$^4$G, Sheth et. al. 2010) is a deep 3.6 and 4.5 $mu$m imaging survey of 2352 nearby ($< 40$ Mpc) galaxies. We describe the S$^4$G data […]

Symplectic integration for the collisional gravitational $N$-body problem

Kavli Affiliate: Edmund Bertschinger | First 5 Authors: David M. Hernandez, Edmund Bertschinger, , , | Summary: We present a new symplectic integrator designed for collisional gravitational $N$-body problems which makes use of Kepler solvers. The integrator is also reversible and conserves 9 integrals of motion of the $N$-body problem to machine precision. The integrator […]

Kepler Eclipsing Binary Stars. VI. Identification of Eclipsing Binaries in the K2 Campaign 0 Data-set

Kavli Affiliate: Saul A. Rappaport | First 5 Authors: Daryll M. LaCourse, Kian J. Jek, Thomas L. Jacobs, Troy Winarski, Tabetha S. Boyajian | Summary: The original {it Kepler} mission observed and characterized over 2400 eclipsing binaries in addition to its prolific exoplanet detections. Despite the mechanical malfunction and subsequent non-recovery of two reaction wheels […]

Higgs sector extension of the neutrino minimal standard model with thermal freeze-in production mechanism

Kavli Affiliate: Mihoko Nojiri | First 5 Authors: Hiroki Matsui, Mihoko Nojiri, , , | Summary: The neutrino minimal Standard Model ({nu}MSM) is the minimum extension of the standard model. In this model, the Dodelson-Widrow mechanism (DW) produces keV sterile neutrino dark matter (DM) and the degenerate GeV heavy Majorana neutrinos lead to leptogenesis. However, […]
