Early Life and Education
Shrinivas Ramchandra Kulkarni was born on October 4, 1956. His hometown is Kurundwad in Maharashtra, India. His family followed the Hindu religion. His father, Dr. R. H. Kulkarni, was a surgeon. His mother, Vimala Kulkarni, was a homemaker.
Shrinivas has three sisters. One of them is Sudha Murthy, a well-known educator and writer. The Kulkarni children grew up in Hubballi, Karnataka, India. They went to local schools there.
Kulkarni studied applied physics at the Indian Institute of Technology, Delhi. He earned his master's degree in 1978. Later, he moved to the United States. He received his PhD from the University of California, Berkeley in 1983.
Discoveries in Astronomy
In 1987, Kulkarni joined the faculty at the California Institute of Technology (Caltech). He is famous for making important discoveries. These discoveries have opened up new areas of study in astronomy. He uses many different types of light (wavelengths) to observe space.
His research covers several exciting areas:
- Studying the Milky Way Galaxy using radio waves.
- Discovering pulsars, which are spinning neutron stars.
- Finding brown dwarfs, which are "failed stars."
- Learning about soft gamma-ray repeaters.
- Investigating gamma-ray bursts, powerful explosions in space.
- Observing optical transients, which are sudden changes in light from space.
Exploring the Milky Way
Kulkarni started his career by studying space using radio waves. He looked at the Milky Way Galaxy and found its four arms. He worked with his advisor, Carl Heiles, on these studies. Their work helped scientists understand the space between stars.
Uncovering Pulsars
While he was a student, Kulkarni made a big discovery. He found the first millisecond pulsar with Donald Backer. This pulsar, called PSR B1937+21, spins incredibly fast.
In 1986, he found the first optical partner of binary pulsars. These are two pulsars orbiting each other. In 1987, he helped discover the first pulsar inside a globular cluster. A globular cluster is a huge group of stars.
Understanding Gamma-Ray Sources
Kulkarni and his team showed that soft gamma-ray repeaters are neutron stars. These neutron stars are linked to supernova remnants. Supernova remnants are what's left after a star explodes. This discovery helped scientists understand that these repeaters are actually magnetars. Magnetars are neutron stars with extremely strong magnetic fields.
In 1997, Kulkarni's team at Caltech and NRAO made another breakthrough. They showed that gamma-ray bursts come from outside our galaxy. They also found the optical light from these bursts. This led to much more detailed studies of these powerful cosmic explosions.
Finding Brown Dwarfs
Kulkarni was also part of the Caltech team that found the first clear brown dwarf in 1994. A brown dwarf is an object that is too big to be a planet but too small to be a star. This one orbited a star called Gliese 229.
New Optical Transients
His more recent work involves the Palomar Transient Factory. This project looks for objects that suddenly become brighter in the sky. They have found new types of these "optical transients." These include superluminous supernovae (very bright star explosions) and luminous red novae (stars that suddenly brighten and turn red).
Kulkarni's research has been very successful. He has published many scientific articles. Because of his important work, he received the Dan David Prize in 2017.
Awards and Honors
Shrinivas Kulkarni has received many important awards and honors.
- In 1991, he won the Helen B. Warner Prize from the American Astronomical Society.
- He received the NSF's Alan T. Waterman Award in 1992.
- In 2002, he was given the Jansky Prize.
- He received the Dan David Prize in 2017.
- In 2015, he was given an honorary doctorate from Radboud University in the Netherlands.
- Most recently, in 2024, he was awarded the Shaw Prize in Astronomy.
Kulkarni is also a member of several important science academies around the world.
- He became a Fellow of the Royal Society in London in 2001.
- He joined the United States National Academy of Sciences in 2003.
- He became an honorary fellow of the Indian Academy of Sciences in 2012.
- In 2016, he became a foreign member of the Royal Netherlands Academy of Arts and Sciences.
