Since 2002, the far-ultraviolet (FUV) flux (1150–1680 Å) of Eta Carinae, monitored by the Hubble Space Telescope/Space Telescope Imaging Spectrograph, has increased by an order of magnitude. This increase is attributed to partial dissipation of a

Interactions of a shock with a molecular cloud at various stages of its evolution due to thermal instability and gravity

Autor: Christopher J. Wareing, M. M. Kupilas, S. A. E. G. Falle, Julian M. Pittard

Using the adaptive mesh refinement code mg, we perform hydrodynamic simulations of the interaction of a shock with a molecular cloud evolving due to thermal instability (TI) and gravity. To explore the relative importance of these processes, three ca

Striations, integrals, hourglasses, and collapse – thermal instability driven magnetic simulations of molecular clouds

Autor: Christopher J. Wareing, Julian M. Pittard, S. A. E. G. Falle

The MHD version of the adaptive mesh refinement (AMR) code, MG, has been employed to study the interaction of thermal instability, magnetic fields and gravity through 3D simulations of the formation of collapsing cold clumps on the scale of a few par

The role of massive stars is central to an understanding of galactic ecology. It is important to establish the details of how massive stars provide radiative, chemical, and mechanical feedback in galaxies. Central to these issues is an understanding

Search for non-thermal X-ray emission in the colliding wind binary Cyg OB2 #8A

Autor: Grégor Rauw, Yaël Nazé, E. Mossoux, Julian M. Pittard

Cyg OB2 #8a is a massive O-type binary displaying strong non-thermal radio emission. Owing to the compactness of this binary, emission of non-thermal X-ray photons via inverse Compton scattering is expected. We first revised the orbital solution for
