My primary research work is focused on different phases of the stellar life cycle using millimeter/sub-millimeter observations, and astrochemical model.

1. ALMA Observation of Young Stellar Object
ALMA 230 GHz continuum map of G28.20-0.05. Contours start at 3σ (1σ = 1 mJy beam⁻¹). The beam (0.22″ × 0.20″, PA = −47°) is shown in the lower-left. White crosses mark three hot molecular cores (HMCs). Insets show molecular line emission peaks, temperature gradients, and dendrogram structures of identified species.

2. ALMA Observations of Asymptotic Giant Branch Stars
ALMA Moment 0 maps of SO2 transitions towards R Dor using ALMA 12m array observations. Contours are drawn with steps of 3σ, 4σ, 5σ, 6σ, 9σ, 12σ, 15σ, 18σ, and 24σ. The beam size is shown at the lower left corner of each subplot as a filled grey ellipse. The cyan cross symbol indicates the position of the continuum peak. The right panel shows the rotational diagram of SO2. Prasanta Gorai et al. 2025, A&A, A31, 21
