Optical spectra of selected Chamaeleon I young stellar objects [PDF]

, 2003
We present optical spectra of eight candidate brown dwarfs and a previously known T Tauri star (Sz 33) of the Chamaeleon I dark cloud. We derived spectral types based on the strength of the TiO or VO absorption bands present in the spectra of these ...

The evolutionary state of young stellar objects in IRDC G48 [PDF]

, 2007
Spitzer Space Telescope mid-infrared (3–24 m) photometry is processed and analyzed in order to assess the young stellar content of Infrared Dark Cloud G48. It is established from color-color diagram analysis that 40 objects are YSO (Young Stellar Object)

Illuminating Youth: Decades of Mid-infrared Variability and Color Evolution of Young Stellar Objects

The Astrophysical Journal Supplement Series
The variability of young stellar objects (YSOs) is a crucial tool for understanding the mechanisms driving flux changes. In this study, we present an infrared variability analysis of a large sample of over 20,000 candidate YSOs, using data from the ...

Natural Killer Cells in Paediatric Soft Tissue Sarcomas: A Systematic Review

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Paediatric soft tissue sarcomas (pSTS) are a rare and heterogeneous group of malignant tumours arising in tissues of mesenchymal origin. The role of natural killer (NK) cells in pSTS remains poorly understood, with evidence fragmented across small preclinical studies and early‐phase clinical trials.

Number ratios of young stellar objects in embedded clusters [PDF]

, 2005
Embedded clusters usually contain young stellar objects in different evolutionary stages. We investigate number ratios of objects in these classes in the star-forming regions ? Ophiuchi, Serpens, Taurus, Chamaeleon I, NGC 7129, IC 1396A and IC 348.
