Transneptunian objects are icy bodies beyond the orbit of Neptune. A large fraction are found in binary pairs, up to ~30% in the Cold Classical population, which generally have components of similar size and colour on widely separated orbits. Understanding what mechanisms have lead to the formation of such a high binary fraction, and their orbital distributions, holds the potential to elucidate th

This thesis presents the results of the first detection of an atmospheric response to a flare induced Sunquake (SQ). Ground-based observations of the Ca II 8542 Å and H-α 6563 Å passbands from the Swedish 1-m Solar Telescope (SST) were used in combination with space-based observations from the Heliosesimic and Magnetic Imager (HMI) onboard the Solar Dynamics Observatory (SDO). Both instruments obs

Wave motions have been detected throughout the solar atmosphere for many decades, and their ability to transport energy through the atmosphere has sparked wide investigation into the role of waves in the heating of the upper solar atmosphere. Strong predominantly vertical magnetic fields within sunspots provide ideal conduits for waves generated by subphotospheric p-modes to propagate upwards thro

With recent developments in technology, instrumental precision is no longer the limiting factor in detecting Earth-analogue exoplanets using the radial velocity (RV) method. Instead, the astrophysical noise caused by stellar activity can mask or, in extreme cases, mimic planetary RV motions. Therefore, this thesis is dedicated to trying to better understanding the impact of stellar activity in ord

Instrumental precision is no longer the biggest impediment to the discovery of Earth-like planets. Indeed, future space missions and next generation spectrographs are technically capable at finding and characterising Earth-analogue planets. However, it is now stellar activity that poses a critical challenge on the pathway to detect habitable Earth-like worlds. This thesis is therefore dedicated to

This thesis presents visual and near-infrared spectroscopic observations of Trans-Neptunian Objects and centaurs obtained over four observing runs at the ESOVery Large Telescope. The reflectance spectra of these minor planets were investigated to determine whether silicates and refractory organics, which are predicted to be present on their surfaces, could be directly detected via the presence of

<p dir="ltr">Physical systems do not have access to every imaginable configuration. Constituents, local laws, relations, environmental conditions, causal structure, and history jointly restrict the set of states that remain physically accessible.

<pre>It is commonly assumed that planets on close orbits cannot survive once their host stars expand into red giants, as stellar radii increase dramatically and tidal forces become destructive. This expectation underpins current views of planetary populations around evolved stars. While a single such system had been reported previously, we show that this phenomenon is not an isolated anomaly. The
