Spectroscopic and photometric monitoring of a poorly known high-luminous OH/IR star: IRAS 18278+0931
Supriyo Ghosh, Soumen Mondal, Ramkrishna Das +1
We present the time-dependent properties of a poorly known OH/IR star IRAS 18278+0931 (hereafter, IRAS 18+09) towards the Ophiuchus constellation. We have carried out long-term…
New Temperature and Metallicity Scale of Cool Giants from K-band Spectra
Supriyo Ghosh, D. K. Ojha, J. P. Ninan
We present here quantitative diagnostic tools for cool giants that employ low-resolution near-infrared spectroscopy in the -band for stellar population studies. In this study, a…
Impact of Particle Arrays on Phase Separation Composition Patterns
Supriyo Ghosh, Arnab Mukherjee, Raymundo Arroyave +1
We examine the symmetry-breaking effect of fixed constellations of particles on the surface-directed spinodal decomposition of binary blends in the presence of particles whose surf…
Finite Interface Dissipation Phase Field Modeling of Ni-Nb under Additive Manufacturing Conditions
Kubra Karayagiz, Luke Johnson, Raiyan Seede +8
During the laser powder bed fusion (L-PBF) process, the built part undergoes multiple rapid heating-cooling cycles, leading to complex microstructures with nonuniform properties. I…
Exact relaxation dynamics and quantum information scrambling in multiply quenched harmonic chains
Supriyo Ghosh, Kumar S. Gupta, Shashi C. L. Srivastava
The quantum dynamics of isolated systems under quench condition exhibits a variety of interesting features depending on the integrable/chaotic nature of system. We study the exact…
Spectral Calibration of KM Giants from medium resolution near-infrared HK-band spectra
Supriyo Ghosh, Soumen Mondal, Ramkrishna Das +1
We present here new medium resolution spectra ( 1200) of KM giants covering wavelength range 1.501.80 and 1.952.45 m. The sample includes 72 K0M8 giants…
