In this module, you’ll learn to quantitatively describe the physics of stars and exoplanets. It introduces the physical concepts underpinning our understanding of these objects and the astronomical techniques used to explore them. Building on these foundations, you’ll get a flavour of cutting-edge findings in selected areas and the opportunity to experience authentic research with your own observational data.
The module comprises four elements which interlink to provide the astrophysical foundations of the discipline and examples of how astrophysical research advances.
Two self-contained texts provide a quantitative account of the physics of stars and exoplanets and the astronomical techniques used to study them.
The text Stars investigates the properties of stars at different stages of evolution – how they form, what happens to them as they age, and what becomes of them when they die. You’ll explore physical processes that sustain stars’ energy output during each stage of evolution and drive the progression from one stage to the next, as well as the relationship between stages of stellar evolution and the production of chemical elements. In addition, you’ll develop your understanding of the basic concepts of hydrodynamics, thermodynamics, plasma physics, quantum physics and nuclear physics.
Exoplanet research saw rapid advances over the last decade, demonstrating that planets around stars other than the Sun are ubiquitous and diverse. Exoplanets explores the photometric and spectroscopic methods used in exoplanet detection and how the physical properties of star/planet systems are derived. The text concludes with an account of how the growing population of planets with known parameters informs our understanding of planet formation.
Alongside studying the two texts, you’ll engage with an observational astronomy project on transiting exoplanets. You’ll have observing time on the OpenScience Observatories’ Tenerife facilities and schedule observations of an exoplanet transit. You’ll obtain transit light curves and analyse the exoplanet’s characteristics.
The module concludes with three case studies relating to more recent research findings in stellar and exoplanetary astrophysics. These findings are conveyed through a series of activities using standard professional astronomy tools.
There are no formal entry requirements for this module.
At The Open University, we believe education should be open to all, so we provide high-quality university education to anyone who wishes to realise their ambitions and fulfil their potential.
Even though there are no entry requirements, you’ll need an appropriate knowledge of mathematics and physics obtained through:

Astrophysics of stars and exoplanets (S384) starts once a year – in October.
It will next start in October 2026.
We expect it to start for the last time in October 2030.
