Three-dimensional mixing and light curves: constraints on the progenitor of supernova 1987A

Victor Utrobin, Annop Wongwathanarat, H. -Thomas Janka +3

With the same method as used previously, we investigate neutrino-driven explosions of a larger sample of blue supergiant models. The larger sample includes three new presupernova s…

O2 signature in thin and thick O2-H2O ices

B. Müller, B. M. Giuliano, L. Bizzocchi +2

Aims. In this paper we investigate the detectability of the molecular oxygen in icy dust grain mantles towards astronomical objects. Methods. We present a systematic set of experim…

Gravitational waves from three-dimensional core-collapse supernova models: The impact of moderate progenitor rotation

H. Andresen, E. Müller, H. -Th. Janka +3

We present predictions for the gravitational-wave (GW) emission of three-dimensional supernova (SN) simulations performed for a 15 solar-mass progenitor with the Prometheus-Vertex…

Structure and kinematics of Type II Cepheids in the Galactic bulge based on near-infrared VVV data

V. F. Braga, A. Bhardwaj, R. Contreras Ramos +5

Type II Cepheids (T2Cs) are radially pulsating variables that trace old stellar populations and provide distance estimates through their period-luminosity (PL) relation. We trace t…

Dramatic X-ray spectral variability of a Compton-thick type-1 QSO at

Torben Simm, Johannes Buchner, Andrea Merloni +6

We report on the discovery of a dramatic X-ray spectral variability event observed in a broad line type-1 QSO. The XMM-Newton spectrum from the year 2000 is characterized…

Improved Leakage-Equilibration-Absorption Scheme (ILEAS) for Neutrino Physics in Compact Object Mergers

Ricard Ardevol-Pulpillo, H. -Thomas Janka, Oliver Just +1

We present a new, computationally efficient, energy-integrated approximation for neutrino effects in hot and dense astrophysical environments such as supernova cores and compact bi…
