In the Newar community of the Kathmandu Valley, the Mohani festival holds specific nuances. The exchange of Sekhar is intertwined with complex kinship networks. Here, the Sekhar is not just about money but about maintaining the Guthi (societal) obligations. The refusal or inability to participate in the exchange of Sekhar can lead to social ostracization,
Recognizing that significant meteor shower outbursts are frequently missed due to localized bad weather or limited camera network coverage, Dr. Sekhar played a crucial role in developing the "Mobile Observation of METeor" (MoMET) device.
: He is a Fellow of the Royal Astronomical Society (FRAS) and an active member of the International Astronomical Union (IAU) .
Aswin Sekhar is a prominent Indian astrophysicist and celestial mechanician, recognized as India's first professional meteor scientist in modern times. His research primarily focuses on the dynamics of solar system bodies, particularly meteoroid streams and their interaction with planetary gravity and relativity.
: His interest in the cosmos was sparked by the pristine, light-pollution-free night skies of his childhood. He credits mentors like Krishna Warrier and novelist Shashi Warrier for encouraging his curiosity. aswin sekhar
Dr. Aswin Sekhar: The Meteor Whisperer Dr. Aswin Sekhar is a pioneering Indian astrophysicist renowned for becoming India's first professional . His work focuses on celestial mechanics, specifically how the gravitational pulls of large planets influence the tiny fragments of space rock that create meteor showers on Earth. Key Scientific Breakthroughs
His published research in journals like Meteoritics & Planetary Science outlines the resonant behavior of the legendary and its associated debris field, the Orionid meteor stream. This work mapping celestial structures aids planetary defense agencies in keeping satellites and space infrastructure safe from high-velocity particle impacts.

The Aswin Sekhar acts as a unique form of wealth redistribution within the clan. For rural households, the preparation for Dashain involves significant liquidity generation to meet the demands of the Sekhar . It creates a seasonal spike in currency demand. For urban, middle-class families, the Sekhar often serves as a "starter fund" for the youth, sometimes amounting to significant savings if pooled from multiple relatives.
But Sekhar’s planetary defense philosophy extends beyond impacts. He argues that we have become fixated on “planet-killers” like the dinosaur-ending Chicxulub impactor, ignoring the far more frequent threat of airbursts (like Chelyabinsk in 2013 or Tunguska). His research advocates for a global, decentralized network of small telescopes to detect meter-sized objects that currently slip past our survey telescopes. "We are not ready for the next Tunguska," he warned in a 2021 lecture, "because we are looking for mountains, not houses." In the Newar community of the Kathmandu Valley,
He should have left it at the shop—pets were a complication—but the dog curled under his arm like a secret and fell asleep against his chest as though it had always belonged there. He named it Memory, half as a joke and half because the name made him feel braver.
What sets Aswin Sekhar apart from a typical astronomer is his philosophical depth. He often quotes Carl Sagan and the Indian poet Vallathol in the same breath. Sekhar views astronomy as a unifying human endeavor. For him, studying asteroids is not merely about saving Earth from impact; it is about recognizing our fragility. Fighting light pollution is not merely about better telescope images; it is about preserving the "awe experience" that gave birth to science, religion, and art.
Dr. Aswin Sekhar is a prominent Indian astrophysicist, meteor scientist, and science communicator. He has earned global recognition for his pioneering work in celestial mechanics, particularly in the study of orbital resonances and the dynamics of meteoroid streams. 🌌 Background and Early Life
: Dr. Sekhar solved a decades-old mystery regarding the Perseid meteor shower . He discovered that a rare "three-body resonance" between the Perseid debris, Jupiter , and Saturn causes meteors to clump together, leading to intense "howling dog" outbursts of bright meteors. The refusal or inability to participate in the
Stood as the batch topper at Christ University, Bengaluru.
Inside, there was no gold, no deed, no treasure map. There was only a small, folded piece of paper and a heavy, brass pocket watch.
His grandparents’ train journeys along the riverbanks became his first astronomy lessons. "My grandparents used to take me to railway stations to catch late-night trains and the sky was simply stellar over the banks of the beautiful Nila River in Kerala," he recalls. This simple exposure to the unspoiled night sky instilled a deep fascination that formal education would later fuel.
