About Me

Welcome to my personal webpage

My research focuses on unraveling the physical and chemical mechanisms governing star and planet formation. To probe these dense and dynamic environments, I utilize multi-wavelength observations—spanning optical, infrared, and  sub-millimeter regimes—from leading international space missions and ground-based facilities.   My primary research centers on protostellar jets, early accretion dynamics, and planet detection around young stars. High-resolution submillimeter data from ALMA allow me to resolve cold gas kinematics and disk structures at fine scales, while infrared imaging and spectroscopy from JWST pierce dense protostellar envelopes to trace shock-excited jet launching regions, organic chemistry, and forming giant planets. A central pillar of my research strategy relies on leveraging Indian national optical and infrared telescope facilities to drive long-term spectroscopic monitoring and high-precision stellar diagnostics. I actively utilize the 3.6-m Devasthal Optical Telescope (DOT) for deep optical and near-infrared spectroscopic characterization of young stellar objects, alongside the Himalayan Chandra Telescope (HCT) for monitoring outflow variability and stellar accretion dynamics. Furthermore, I am heavily interested in high-resolution time-domain optical spectroscopy using PARAS-2 on the 2.5-m Mount Abu Telescope, measuring precision radial velocities, accretion rates, and line-profile asymmetries to constrain magnetospheric accretion, stellar winds, and early planet-forming environments.

Project I: Protostellar Jets/Outflows and Planet Formation
Outflows and jets are the most intriguing characteristics of protostars during the accretion process. They remove excess angular momentum from the disk surface, allowing accreting material to fall onto the star surface. The origin and characteristics are still unclear. High-resolution and high-sensitivity observations with Atacama Large Millimeter Array - ALMA in the submillimeter wavelength provides a robust opportunity to explore the characteristics of the jets. Observations of statistically significant jets allow drawing a comprehensive picture of the jet's characteristics. A few AU scale observations with higher velocity resolution allow to measure jet rotation as well as jet-launching radius (ref: ALMASOP project; Dutta et al. 2020; 2022a; 2022b & 2024 )

Planets are thought to form within protoplanetary disks at their very early evolutionary stage. Observations and simulations have indicated possible signs of planet formation within these disks. However, the exact process and timeline for the beginning of their formation are not yet fully understood, and further detailed investigation is needed. We are working on the emission from the dust continuum and molecular line within the disk, and model the structures to identify potential substructures associated with planet formation.

Dense Cores, Molecular Outflow and Jets, the Birth Places of Stars and Planets
Dense cores are incredible targets for investigating the initial condition of star formation, jet morphology, chemical evolution, and planet formation. To explore multiple goals, we have been investigating a set of dense cores. Slide (1) displays the location of such dense cores in the Orion molecular Cloud Complex. Slide (2) presents examples of continuum emission of different kinds of dense cores. Slide (3) shows examples of outflow emission of already formed protostars within dense cores. Slide (4) shows the chemical composition of Hot corinos within dense cores. Slide (5) displays molecular jets and associated knots for two stars, one of them is the most evolved protostar with a molecular jet. Slide (6) is one of the youngest molecular jets. Molecular jets could be monopolar or bipolar. Slide (7) provides some examples of monopolar jets. Slide (8) shows some examples of bipolar jets.	(1) (2) (3) (4) (5) (6) (7) (8) Previous Next

Project II: Radio Instrumentation and Data processing
First Radio Burst (FRB) has been a topic of immense attraction for the last few years due to the challenges of their detection and localization. Recently, the Taiwanese FRB community launched a new radio telescope, Bustling Universe Radio Survey Telescope in Taiwan (BURSTT) , dedicated for detection and localization of FRBs. Due the technical challenges, I am interested in their localization using very large baseline interferometric (VLBI) observations. There are several outrigger stations of the BURSTT projects as a part of VLBI observations Lin et al. 2022. I am involved in the installation, calibration and data processing of the telescope with out the BURSTT collaboration. I am particularly leading one BURSTT outrigger station at Raman Research Institute (RRI), Bangalore, India.

Project III: Formation of Young Star Cluster
The formation of the star cluster is a topic of considerable interest since most stars in our Galaxy form in groups within clustered environments. Several environmental conditions can breed young clusters. As molecular clouds are often composed of HIIregions, bubbles, and dense filamentary structures , understanding what shapes the molecular clouds to be dense and massive enough to form a young cluster is therefore of great interest. Additionally, the initial cloud configuration decides the future location of cluster formation. Therefore, the exact role of environment on the star and star cluster formation of a cloud can only be thoroughly understood by tracing various components of the interstellar medium (ISM) through multiwavelength observations. We utilize multiwavelength (sub-millimeter, radio 1.4 GHz, infrared, optical) observed data to explore the star and star cluster formation (Ref: (Dutta et al. 2015, 2018b )

Project IV: Time-Series photometry of young objects
Photometric variability is a ubiquitous characteristic of young stars. In a binary system, two components eclipse one another periodically, resulting in a change in the apparent brightness of the system. Furthermore, various temporal phenomena such as flare-like activity on the corona, circumstellar disc extinction due to disc asymmetry, variable accretion rates, etc., can lead to aperiodic variability of young stars. Potentially, variability explores the young stars in the field population. We performed optical monitoring of young star clusters with optical telescopes 2m HCT, India 1.3m DFOT, India; 1.04-m ST, India) to explore the variability characteristics of the young stars (ref: Dutta et al. 2018a & Dutta et al. 2019.
