“…studied far infrared (60 µm and 100 µm) IRAS loop at -5 o Galactic latitude around pulsar J1627-5547 by taking different dust properties like Dust Color Temperature, Dust Mass, and Inclination angle and they conclude that the results are agreed with Gaussian similar works are also done by Chaudhary et al (2022). Several research has been performed exploring the properties of interstellar dust using the infrared data in the region near the Pulsars [10,11] , White Dwarfs [12,13] , AGB Star [14,15] , Supernova Remnants [16] , FIR loops [17,18] , FIR Cavities [19] , etc., using the data from IRAS, IRIS, and AKARI. In this work, we have studied the multiwavelength variation of dust color temperature together with dust mass near the pulsar J0302+2252 using IRIS, AKARI, and WISE surveys.…”

A search of dust structure nearby the pulsar J0302+2252 in IRIS , AKARI and WISE survy was performed using Skyview Observatory (http://skyview.gsfc.nasa.gov). The physical properties have been studied at 60µm & 100µm in the IRIS survey, 90µm & 140µm in the AKARI survey and 12µm & 22µm in the WISE survey at right ascension (R.A.) (J2000)=30h(_^) 02m 31.99s and Declination (Decl.) (J2000)=+ 220 52m 12.10s . In this work, we have studied the physical properties such as Dust color temperature, Planck’s unction, Visual extinction and Mass profile of the dust data reduction software ALADIN v11. The dust color temperature is found to be 22.271 ± 0.261K in IRIS, 22.343 ± 0.939 K in AKARI and 278.74 ± 0.067 K in WISE. Also, the dust mass is found to be 2.286 × 1027 kg (1.149 × 10-3 M⊙ ) in IRIS, 8.800 ×1027 kg (0.416× 10-3 M⊙ ) in AKARI and 5.220 ×1025 kg (0.026 ×10-3 M⊙ ) in WISE. The average visual extinction is found to be 1.372 ×10-13 mag. In IRIS, 4.970 ×10-14 mag. In AKARI and 1.673 ×10-15 mag. In WISE. The dust color temperature and dust mass distribution show a very good agreement with Gaussian. The Contour plots of dust color temperature and dust mass show inverse relation between them in all three bands IRIS, AKARI, and WISE.

“…In past, many research has been performed exploring the properties of interstellar dust using the infrared data in the region near the Pulsars [8,9], White Dwarfs [10,11], AGB Star [12,13], Supernova Remnants [14,15], FIR loops [16][17][18][, FIR Cavities [18,19], Isolated Nebula [20], etc., using the data from IRAS, IRIS and AKARI. In this work, we have used the data from IRIS and AKARI to explore the properties of dust within the molecular cloud.…”

In this work, we have studied the dust properties of the North-East part of Perseus cloud having a size of 0.5o × 0.5o located at RA (ICRS): 56.14o DEC (ICRS): +32.15o, within the Open Cluster IC 348, using IRIS and AKARI data. An isolated region of size 0.39o×0.23o in IRIS and 0.34o×0.16o in AKARI data is detected within it. The infrared fluxes extracted using Aladin v11.0 are used to study the dust temperature and dust mass. The distance of the selected dust structure is calculated using Gaia EDR3, which is 309.98 pc. The infrared flux density is found to be increased for long-wavelength data. The average dust color temperature calculated from short-wavelength IRIS data is more than that calculated from long-wavelength AKARI data, which are 26.34 K±0.11 K for IRIS and 17.63 K±0.02 K for AKARI data. The mass of dust within the entire dust structure is 0.06 Mʘ for IRIS data and 37.44 Mʘ for AKARI data. Jeans mass for isolated region gives contradictory results in two surveys, for IRIS survey total mass is smaller than Jeans mass but for AKARI survey the total mass is larger than the Jeans mass. A good correlation between infrared fluxes is noticed for linear regression. The study background sources observed from the SIMBAD database explore the large number of stars, X-ray sources, YSOs, etc., embedded within the dust structure; some of them are responsible for dust heating and some for the contribution of dust mass. The contour map shows the identical distribution between infrared fluxes, dust color temperature and Planck’s function and dissimilar distribution between dust mass and visual extinction in IRIS and AKARI data. The high temperature at the central region suggests that the core of dust structure is thermally active, radiating the large thermal radiation in comparison to the outer region.
