Progress in Diamanes and Diamanoids Nanosystems for Emerging Technologies

Advanced Science, Volume 9, Issue 11, April 14, 2022., 2022
Diamanes and diamanoids are newly discovered graphitic carbon nanostructures. These nanosystems are sp3 carbon networks along with few sp2 hybridized carbon atoms which can be fabricated under controlled temperature & pressure using graphitic system as a precursor.

PHANGS–JWST First Results: Duration of the Early Phase of Massive Star Formation in NGC 628

The Astrophysical Journal Letters, 2023
The earliest stages of star formation, when young stars are still deeply embedded in their natal clouds, represent a critical phase in the matter cycle between gas clouds and young stellar regions.

A Spitzer Space Telescope Infrared Survey of Supernova Remnants in the Inner Galaxy [PDF]

, 2005
Using Infrared Array Camera (IRAC) images at 3.6, 4.5, 5.8, and 8 μm from the GLIMPSE Legacy science program on the Spitzer Space Telescope, we searched for infrared counterparts to the 95 known supernova remnants that are located within Galactic ...

Visible to Mid‐Infrared Optical Constants of Orthopyroxenes

Earth and Space Science, Volume 9, Issue 4, April 2022., 2022
Abstract Radiative transfer models of remotely acquired infrared spectra result in quantitative identification of minerals on planetary surfaces. Optical constants, or the real (n) and imaginary (k) indices of refraction are necessary inputs in such models.

An investigation of open cluster Melotte 72 using Gaia DR2

Astronomische Nachrichten, Volume 342, Issue 4, Page 613-624, May 2021., 2021
Abstract The estimation of the main parameters of star clusters is significant in astrophysical studies. The most important aspect of using the Gaia DR2 survey lies in the positions, parallax, and proper motions of cluster stars with homogeneous photometry that make the membership probability determine with high accuracy.

1I/‘Oumuamua as an N2 Ice Fragment of an exo‐Pluto Surface: I. Size and Compositional Constraints

Journal of Geophysical Research: Planets, Volume 126, Issue 5, May 2021., 2021
Abstract The origin of the interstellar object 1I/‘Oumuamua has defied explanation. We perform calculations of the non‐gravitational acceleration that would be experienced by bodies composed of a range of different ices and demonstrate that a body composed of N2 ice would satisfy the available constraints on the non‐gravitational acceleration, size ...
