This module comprises four lecture courses which extend knowledge gained in the first level module AS1001, and discuss recent developments in the subject: (i) observational techniques - modern telescopes; instruments and detectors for gamma-, X-, uv, optical, IR and radio radiation; spherical astronomy and essential coordinate systems; (ii) the structure and evolution of stars - nucleosynthesis, stellar properties as a function of age, a complete understanding of the HR diagram; (iii) exoplanetary science - theoretical and observational studies of planetary systems beyond our own; (iv) galactic astronomy - the distribution and motion of stars, gas, dust, and dark matter in our Milky Way and other galaxies.

To introduce students to a broad range of topics across modern astrophysics. To develop problem solving skills through tutorial and laboratory sessions.
Learning Outcomes
Familiarity with a broad range of topics in modern astrophysics;
Strengthening of the skills learned in AS1001/AS1101 and level 1 physics and mathematics modules;
Improved ability to analyse astronomical data, including the use of relevant software;
Ability to formulate and solve quantitative problems by applying physical concepts and mathematical tools up to the level of differential and integral calculus to astrophysical systems.
Synopsis
Exoplanetary science
This course looks at the formation of planets in circumstellar
accretion discs and the implication for internal structures of gas-giant and terrestrial-like planets.
Theoretical models and observational techniques are discussed.
Observational Techniques
This course provides an overview of the multi-wavelength observational techniques that underpin modern astrophysics, including telescope and instrument design, photometry and spectroscopy, the effects of the Earth’s atmosphere (and approaches to mitigating them), and astronomical coordinate systems and source observability.
Stellar Structure and Evolution
The determination and distribution of stellar masses, radii and luminosities; the Hertzsprung-Russell diagram, mass-luminosity law and Vogt-Russell theorem. Sources of stellar energy, nucleosynthesis of hydrogen, helium and carbon. Star formation and evolution; the ages of star clusters; supernova events and the synthesis of heavy elements. Final states - white dwarfs, neutron stars (pulsars) and black holes.
Galactic Astronomy
This course will investigate the distribution and motions of stars, gas and dust within our own galaxy in order to determine its dimensions and overall properties. Properties of other galaxies will be discussed.
Topics include: galactic coordinate systems; the solar motion and distribution of stellar velocities; differential galactic rotation, the rotation velocity at the Sun and the distance to the Galactic Centre; rotation curves of the Milky Way and other galaxies; galaxy masses and "dark" matter.
Accreditation Matters
This module may not contain material that is part of the IOP “Core of Physics”, but does contribute to the wider and deeper learning expected in an accredited degree programme. The skills developed in this module, and others, contribute towards the requirements of the IOP “Graduate Skill Base”.
