High Honor for Lakshmi Pradeep Chitta
The Karen Harvey Prize recognizes young researchers who have made significant contributions to solar research early in their careers.
To the point:
- High honor: The Solar Physics Division (SPD) of the American Astronomical Society (AAS) has awarded this year's Karen Harvey Prize to MPS researcher Dr. Lakshmi Pradeep Chitta.
- Hot solar atmosphere: In his research, Chitta studies the corona, the Sun’s hot atmosphere. This is where the solar wind and solar flares originate.
- Deeper understanding: Chitta's findings have transformed our understanding of the Sun. They demonstrate how tiny magnetic structures and processes determine the dynamic nature of the corona.
The corona, the Sun's hot outer atmosphere, is a key region for understanding our star. It is the scene of constant transformation processes: magnetic energy is discharged there, generating enormous temperatures of more than a million degrees in some places and providing the “motor” for the solar wind as well as for violent eruptions of particles and radiation. Lakshmi Pradeep Chitta's research thrives in this “solar cauldron” of rapidly changing magnetic fields and plasma flows. Over the past ten years, the researcher at the Max Planck Institute for Solar System Research (MPS) has succeeded in significantly changing our view of this region. His research results show how small-scale and rapid processes work together to produce fundamental properties of the Sun’s corona.
One example is the solar wind. For a long time, it was unclear which processes on the Sun launch the constant stream of particles into space, that travel at supersonic speeds. Chitta identified tiny bursts of radiation, known as picoflare jets, as the driving force. Equally groundbreaking is his research on coronal heating, i.e., the processes that generate the corona’s incredibly high temperatures. Chitta discovered a crucial heat source at the footpoints of hot, loop-shaped plasma flows in the corona: when delicate, braided magnetic field lines untangle and rearrange themselves there, enormous amounts of energy are released.
Chitta's latest research findings concern solar eruptions. Such bursts of radiation and particles can spread towards Earth, paint auroras into the night sky, and even disrupt communication systems and power supplies. Chitta's analyses show how small restructuring processes in the coronal magnetic field can grow like an avalanche and ultimately trigger a violent eruption.
For his research, Chitta uses the latest observational data, such as that provided by the balloon-borne Sunrise solar observatory and the ESA's Solar Orbiter spacecraft. Both solar observatories image different layers of the Sun’s atmosphere, including its surface, in unprecedented detail. In his analyses, Chitta combines this high-precision view of the Sun with computer simulations to gain a deep understanding of the underlying phenomena and processes.
About the award winner and the award
Already in his doctoral thesis, Dr. Lakshmi Pradeep Chitta turned to the Sun’s corona. After PhD studies at the Indian Institute of Astrophysics along with a Predoctoral fellowship at the Harvard-Smithsonian Center for Astrophysics in the USA, he joined the MPS in 2015. His previous achievements include a Marie Sk?odowska-Curie Fellowship from the European Union (2017), the Early Career Researcher Prize from the European Solar Physics Division of the European Physical Society (2019), and a Starting Grant from the European Research Council (2022).
The Solar Physics Division (SPD) of the American Astronomical Society (AAS) awards the Karen Harvey Prize annually to a researcher who has made a significant contribution to the field of solar research early in their career. This year's Karen Harvey Prize will be presented at the 57th meeting of the Solar Physics Division from 9 to 14 August in Baltimore, USA.
Previous winners of the Karen Harvey Prize include MPS Director Prof. Dr. Laurent Gizon and Prof. Dr. Hui Tian, who heads a partner group of the MPS at Peking University.
