On possibility of detection of emission from nanodiamonds in vicinity of stellar objects: laboratory spectroscopy and observational data

TL;DR

This paper explores a new method to detect nanodiamonds near stellar objects by using a specific emission band, supported by laboratory spectroscopy and initial observational data.

Contribution

It introduces a novel detection approach for astrophysical nanodiamonds based on laboratory spectral characterization and preliminary observational results.

Findings

Identification of the 7370 Å emission band as a detection marker

Laboratory spectroscopy confirms the presence of lattice defect emissions

Preliminary observational data support the detection method

Abstract

Based on extensive laboratory characterization of presolar nanodiamonds extracted from mete-orites, we have proposed a novel approach to detect nanodiamonds at astrophysical objects using the 7370 {\AA} emission band arising from lattice defects. Details of laboratory spectroscopic studies and preliminary results of observations are presented.
