On the near - infrared halo of Elias 1
نویسندگان
چکیده
We present new near-infrared speckle interferometric observations of the young stellar object Elias 1. The emission is resolved into a narrow east-west elongated blue halo (FWHM about 0. ′′2x1. ′′0) and an unresolved core (FWHM < 0. ′′2). Previously, Kataza and Maihara (1991) had inferred an east-west elongated optically thin disk within which the NIR light is directly scattered. Adding new pieces to the puzzle may alter the scenario in favor of scattering in bipolar lobes with a polar axis oriented east-west.

Determination of Protein and Moisture in Fishmeal by Near-Infrared Reflectance Spectroscopy and Multivariate Regression Based on Partial Least Squares
The potential of Near Infrared Reflectance Spectroscopy (NIRS) as a fast method to predict the Crude Protein (CP) and Moisture (M) content in fishmeal by scanning spectra between 1000 and 2500 nm using multivariate regression technique based on Partial Least Squares (PLS) was evaluated. The coefficient of determination in calibration (R2C) and Standard Error of Calibra...

Introduction: The photo-thermal therapy by nanoparticles has been recently known as an efficient strategy for the cancer treatment. Carbon nanotubes (CNTs) have been extensively studied in biomedical application due to the easy uptake and high permeability in the cells, biocompatibility in biological environments and also their unique electrical, thermal properties. They genera...
متن کاملA dual role of divalent metal ions in catalysis and folding of RNase H1 from extreme halophilic archaeon Halobacterium sp. NRC-1
RNase H1 from extreme halophilic archaeon Halobacterium sp. NRC-1 (Halo-RNH1) consists of an N-terminal domain with unknown function and a C-terminal RNase H domain. It is characterized by the high content of acidic residues on the protein surface. The far- and near-UV CD spectra of Halo-RNH1 suggested that Halo-RNH1 assumes a partially folded structure in the absence of salt and divalent metal...

متن کاملPolarimetric Differential Imaging of the Class I Protostar
We present near-IR Adaptive Optics (AO) dual polarimetric observations of Elias 2–29, a Class I protostar in the Rho Ophiuchi star forming region. The main goal of these observations is to analyze the close environment of Elias 2–29 in order to derive the properties of its circumstellar disk and envelope. Elias 2–29 is known to be surrounded by circumstellar material (e.g. Boogert et al. 2000)....
