Division on Solar-Terrestrial Sciences

President: Emilia Kilpua (st@egu.eu)
Deputy President: Olga Malandraki (omaland@astro.noa.gr)

The Division on Solar-Terrestrial Sciences (ST) considers all aspects of solar and heliospheric physics, specifically the solar-terrestrial connection. It covers the physical processes occurring on the Sun, in the solar wind, as well as in Earth’s magnetosphere and ionosphere. Solar activity (e.g. coronal mass ejections, solar flares, solar energetic particle events) and the response of the near-Earth space environment to these solar phenomena are studied on a wide-range of temporal and spatial scales. Data analysis and interpretation of space-borne and ground-based data, as well as theoretical studies and different modelling techniques are used to better our understanding of how our local star defines the neighbourhood that we live in.

Exploring Magnetosheath Jets and their dependence on Solar Wind structures

Dayside of the Earth’s magnetic field Our understanding of the relationship between Earth’s magnetic field and the particles from the Sun that constantly bombard it, known as the solar wind, has significantly advanced in recent decades. The availability of numerous spacecraft measurements has provided valuable insights into this interaction. The solar wind, composed of high-speed particles carrying the interplanetary magnetic field from the Sun, undergoes a rapid deceleration as it collides with Earth’s magnetic field. This deceleration creates a shockwave, …


Why faculae “vanish” on active Suns

The Earth’s primary energy source is the radiative energy flux (i.e., the Total Solar Irradiance, TSI) from the Sun. Understanding the TSI or the solar irradiance output in particular wavelengths is important, as it is crucial for sustaining life of metabolisms on Earth and in answering the question of how life emerged on Earth. It has been shown that magnetic activity on the solar surface is one of the main causes of solar irradiance variations. Manifestations of the magnetic activity …


Events organised by the ST-ECS Team during EGU23

The General Assembly is around the corner, and we would like to advertise the events the early-career scientist (ECS) Team of our Division have been preparing to create networking opportunities for ECSs. Joint picnic for ST/PS/AS/EMRP ECSs (in-person only) When? Monday 24 April, 12:30–13:45 CEST Where? Meeting near the main entrance of the Austrian Center Vienna (ACV), before heading out to the Donaupark. What? The early-career scientist (ECS) teams of the ST, PS, AS and GMPV Divisions organise a joint …

Current issue of the EGU newsletter

In a first-of-its kind analysis of the Antarctic ice sheet, researchers Ronja Reese and Emily Hill break down their ice loss study and reveal a small window of hope; while dendrochonrologist Nazimul Islam tells us how tree rings act as one of the finest proxies for studying past climate, hydrology, archaeology and more.

Meanwhile, EGU Policy Manager Chloe Hill dissects the Science Europe publication, Science–Policy in Action: Insights for the Green and Digital Transition, and its relation to climate change, biodiversity loss and digital technologies. And EGU’s Media Survey reveals that despite willingness to speak to the media, journalists say scientists often do not follow through, fearing their science will be misrepresented. If you are a scientist or researcher yourself, do you agree with this? Let us know at media@egu.eu
