Time-resolved plasmon-assisted generation of optical-vortex pulses
Autor: Esra Ilke Albar, Franco P. Bonafé, Valeriia P. Kosheleva, Sebastian T. Ohlmann, Heiko Appel, Angel Rubio
Publikováno v: Scientific Reports, Vol 13, Iss 1, Pp 1-9 (2023)
Abstract The microscopic mechanism of the light-matter interactions that induce orbital angular momentum (OAM) in electromagnetic fields is not thoroughly understood. In this work, we employ Archimedean spiral vortex generators in time-resolved numer

Gravitational wave emission from dynamical stellar interactions
Autor: Javier Morán-Fraile, Fabian R. N. Schneider, Friedrich K. Röpke, Sebastian T. Ohlmann, Rüdiger Pakmor, Theodoros Soultanis, Andreas Bauswein
Publikováno v: Astronomy and astrophysics 672, A9 (2023). doi:10.1051/0004-6361/202245109
We are witnessing the dawn of gravitational wave (GW) astronomy. With currently available detectors, observations are restricted to GW frequencies in the range between ${\sim} 10\,\mathrm{Hz}$ and $10\,\mathrm{kHz}$, which covers the signals from mer

Long-term evolution of a magnetic massive merger product
Autor: Ph. Podsiadlowski, Ruediger Pakmor, Friedrich K. Röpke, Sebastian T. Ohlmann, Steven A. Balbus, Fabian Schneider
Publikováno v: Monthly Notices of the Royal Astronomical Society. 495:2796-2812
About 10% of stars more massive than ${\approx}\,1.5\,\mathrm{M}_\odot$ have strong, large-scale surface magnetic fields and are being discussed as progenitors of highly-magnetic white dwarfs and magnetars. The origin of these fields remains uncertai

Bipolar planetary nebulae from common-envelope evolution of binary stars

Publikováno v: Astronomy and Astrophysics
Astronomy & Astrophysics
Asymmetric shapes and evidence for binary central stars suggest a common-envelope origin for many bipolar planetary nebulae. The bipolar components of the nebulae are observed to expand faster than the rest and the more slowly expanding material has

From 3D hydrodynamic simulations of common-envelope interaction to gravitational-wave mergers
Autor: Melvin M. Moreno, Fabian R. N. Schneider, Friedrich K. Röpke, Sebastian T. Ohlmann, Rüdiger Pakmor, Philipp Podsiadlowski, Christian Sand
Modeling the evolution of progenitors of gravitational-wave merger events in binary stars faces two major uncertainties: the common-envelope phase and supernova kicks. These two processes are critical for the final orbital configuration of double com

Hydrodynamical moving-mesh simulations of the tidal disruption of stars by supermassive black holes
Autor: F. G. Goicovic, Volker Springel, Rüdiger Pakmor, Sebastian T. Ohlmann
Publikováno v: Monthly Notices of the Royal Astronomical Society. 487:981-992
When a star approaches a black hole closely, it may be pulled apart by gravitational forces in a tidal disruption event (TDE). The flares produced by TDEs are unique tracers of otherwise quiescent supermassive black holes (SMBHs) located at the centr

Publikováno v: Gronow, S, Collins, C, Ohlmann, S T, Pakmor, R, Kromer, M, Seitenzahl, I R, Sim, S A & Röpke, F K 2020, ' SNe Ia from double detonations: Impact of core-shell mixing on the carbon ignition mechanism ', Astronomy & Astrophysics, vol. 635 . https://doi.org/10.1051/0004-6361/201936494
Sub-Chandrasekhar mass white dwarfs accreting a helium shell on a carbon-oxygen core are potential progenitors of normal Type Ia supernovae. This work focuses on the details of the onset of the carbon detonation in the double detonation sub-Chandrase
