Fictions, Conditionals, and Stellar Astrophysics [PDF]
, 2013 This article argues in favour of an inferential role for fictions in scientific modelling. The argument proceeds by means of a detailed case study, namely models of the internal structure of stars in stellar astrophysics.

Influence of surface stressing on stellar coronae and winds [PDF]
, 2013 STFC funding has supported this research.The large-scale field of the Sun is well represented by its lowest energy (or potential) state. Recent observations, by comparison, reveal that many solar-type stars show large-scale surface magnetic fields that ...

Separatrix divergence of stellar streams in galactic potentials [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACTFlattened axisymmetric galactic potentials are known to host minor orbit families surrounding orbits with commensurable frequencies. The behaviour of orbits that belong to these orbit families is fundamentally different than that of typical orbits with non-commensurable frequencies. We investigate the evolution of stellar streams on orbits near

The Astrophysical Journal, 2022 Stellar streams from globular clusters (GCs) offer constraints on the nature of dark matter and have been used to explore the dark matter halo structure and substructure of our Galaxy. Detection of GC streams in other galaxies would broaden this endeavor

Dynamics of stellar and HI streams in the Milky Way halo
EPJ Web of Conferences, 2012 Stellar streams are key players in many aspects of Milky Way studies and, in particular, studying their orbital dynamics is crucial for furthering our understanding of the Milky Wayʼs gravitational potential.

Open Astronomy, 2021 We introduce the application of the clustering algorithm to the preliminary compiled list of probable wide pairs of co-moving stars. The main aim of such development is a possibility of unsupervised blind search of coeval loose stellar structures over ...

From theoretical stellar spectra to realistic models of the Milky Way : a never ending Odyssey [PDF]
, 2007 The last chapter is dedicated to the compilation of the results and the discussion about the success of - but also about the problems that have arisen during - and in part also survived - this work. The main goal of this thesis was, firstly, to convert

On the structure of tidally disrupted stellar debris streams [PDF]
Monthly Notices of the Royal Astronomical Society, 2016 A tidal disruption event (TDE) -- when a star is destroyed by the immense gravitational field of a supermassive black hole -- transforms a star into a stream of tidally-shredded debris. The properties of this debris ultimately determine the observable signatures of TDEs.
