Stellar wind disrupting star formation in Orion Nebula: NASA

Published

on

Washington, Jan 8 (IANS) The stellar wind from a newborn star in the Orion Nebula is preventing more new stars from forming nearby, according to a new research.

This is surprising because until now, scientists thought that other processes, such as exploding stars called supernovae, were largely responsible for regulating the formation of stars.

But NASA’s Stratospheric Observatory for Infrared Astronomy (SOFIA)’s observations suggest that infant stars generate stellar winds that can blow away the seed material required to form new stars, a process called feedback.

SOFIA is a Boeing 747SP jetliner modified to carry a 106-inch diameter telescope.

“The wind is responsible for blowing an enormous bubble around the central stars,” said lead author Cornelia Pabst, doctoral student at the University of Leiden in the Netherlands.

“It disrupts the natal cloud and prevents the birth of new stars.”

The Orion Nebula is among the best observed and most photographed objects in the night sky. It is the closest stellar nursery to Earth, and helps scientists explore how stars form.

At the heart of the nebula lies a small grouping of young, massive and luminous stars.

Observations from SOFIA’s instrument the German Receiver for Astronomy at Terahertz Frequencies (GREAT) revealed that the strong stellar wind from the brightest of these baby stars, designated as Theta1 Orionis C, has swept up a large shell of material from the cloud where this star formed, like a snow plow clearing a street by pushing snow to the road’s edges.

At the centre of the Orion Nebula, the stellar wind from Theta1 Orionis C forms a bubble and disrupts star birth in its neighbourhood. At the same time, it pushes molecular gas to the edges of the bubble, creating new regions of dense material where future stars might form.

These feedback effects regulate the physical conditions of the nebula, influence the star formation activity and ultimately drive the evolution of the interstellar medium — the space between stars filled with gas and dust.

“Understanding how star formation interacts with the interstellar medium is key to understanding the origins of the stars we see today, and those that may form in the future,” the researchers said.

She said, “It is our good fortune to have received the joy of doing this noble work today through Foodman Vishal Singh. I have taken another step forward in carrying my family’s values and cooperation by joining hands with the Vijay Shree Foundation. My father taught me to serve and help the needy, and I feel happy when I bring a smile to someone’s face.”

On the birth anniversary of the late Veena Verma, the event organizer, Vijay Shree Foundation founder Foodman Vishal Singh, said, “We feel proud and happy that Dr. Abhishek Verma, a globally renowned business tycoon, has extended his support to uplift our country from the hunger index. Today, on his mother’s birth anniversary, he inaugurated a state-of-the-art permanent shelter at Lucknow Medical College, which will always be helpful for the needy attendants of patients. It is a pleasure for me and the organization to receive the affection of Mr. Verma.”

The event was attended by General Manager Verma Family Office Hemant Garg, Sonu Rajput, and the organization’s volunteers, including Sandeep Singh, Parmeshwar Ji, Prashant Rao Gautam, Balram Singh, Ramesh Chaudhary, Suman, Jeetu, Anil, Suraj, Vinay, Manish Bhadauria, Manas Mehrotra, Vivek, Apurv, Happy, and others.
