Stellar kinematics in disk galaxies [PDF]

open access: yes, 2000
n this thesis several aspects of the stellar kinematics in disk galaxies have been addressed. Due to the low surface brightness of these systems the number of studies that have addressed these issues has been fairly limited.

Internal kinematics of stellar populations in Terzan 5 [PDF]

open access: yes, 2022
openGlobular clusters are stellar systems populated by up to millions of old stars very tightly gravitationally bound. Their absolute ages provide lower limits to the age of the Galactic bulge and the Universe, that can be compared with the one obtained ...

Fictions, Conditionals, and Stellar Astrophysics [PDF]

open access: yes, 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]

open access: yes, 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 ...

Spatially resolved gas and stellar kinematics in compact starburst galaxies

open access: yes, 2022
Context. The kinematics of galaxies provide valuable insights into their physics and assembly history. Kinematics are governed not only by the gravitational potential, but also by merger events and stellar feedback processes such as stellar winds and ...

The SAMI Galaxy Survey: revisiting galaxy classification through high-order stellar kinematics [PDF]

open access: yes, 2017
Recent cosmological hydrodynamical simulations suggest that integral field spectroscopy can connect the high-order stellar kinematic moments h3 (~skewness) and h4 (~kurtosis) in galaxies to their cosmological assembly history.

Mg II/CIV Kinematics vs. Stellar Kinematics in Galaxies [PDF]

open access: yes, 2003
Comparisons of the kinematics of MgII absorbing gas and the stellar rotation curves in 0.5 ≤ z ≤ 1.0 spiral galaxies suggests that, at least in some cases, the extended gaseous envelopes are dynamically coupled to the stellar matter. A strong correlation

From theoretical stellar spectra to realistic models of the Milky Way : a never ending Odyssey [PDF]

open access: yes, 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
