چکیده

We present near-and mid-infrared images of the young stellar object N 160A-IR in the Large Magel-lanic Cloud (LMC). For the rst time, the YSO is seen in the NIR as a compact point source in the northwestern part of the H ii region N 160A. Furthermore, we present ISO-SWS spectra pointed on the YSO. The spectra cover the full wavelength range of SWS on board of ISO (2.5-45 m) where most of the dust features are located. N 160A-IR shows the unidentiied infrared bands (UIBs) and silicate absorption on a steeply rising continuum plus ne structure lines from the H ii region. A radiative transfer model for the YSO with a luminosity of 1:4 10 6 L being deeply embedded (A V =60 mag) in its parental cloud reproduces the observations. The mass of the model cloud is 50,000M consistent with other estimates.

Effects of Low-Intensity Resistance versus High-Intensity Interval Aerobic Training on Serum Interleukin-6 Concentration and Insulin Resistance Markers in Obese and Young Men

Introduction: Regular exercise training is a useful strategy to reduce inflammatory markers, but it is still unclear what type of training is better. Thus, this study compared the effects of 12-week of low-intensity resistance (Low-RT) and high-intensity interval aerobic training (High-IAT) on serum interleukin (IL)-6 levels and insulin resistance (IR) markers in obese and young men. Methods I...

Stellar Populations in the Central Galaxies of Fossil Groups

It is inferred from the symmetrical and luminous X-ray emission of fossil groups that they are mature, relaxed galaxy systems. Cosmological simulations and observations focusing on their dark halo and inter-galactic medium properties confirm their early formation. Recent photometric observations suggest that, unlike the majority of non-fossil brightest group galaxies (BGGs), the central early-t...

Relativistic Stellar Models with Quadratic Equation of State

In this paper, we have obtained and presented new relativistic stellar configurations considering an anisotropic fluid distribution with a charge distribution and a gravitational potential Z(x) that depends on an adjustable parameter. The quadratic equation of state based on Feroze and Siddiqui viewpoint is used for the matter distribution. The new solutions can be written in terms of elementar...

Properties of Circum(sub)stellar Accretion Disks

We have completed a systematic survey for disks around young brown dwarfs and very low mass stars. By choosing a well-defined sample and by obtaining sensitive thermal IR observations, we can make an unbiased measurement of the disk fraction around such low mass objects. We find that ≈75% of our sample show intrinsic IR excesses, indicative of circum(sub)stellar disks. We discuss the physical p...

un 2 00 6 An equatorial wind from the massive young stellar object S 140 IRS 1

The discovery of the second equatorial ionized stellar wind from a massive young stellar object is reported. High resolution radio continuum maps of S140 IRS 1 reveal a highly elongated source that is perpendicular to the larger scale bipolar molecular outflow. This picture is confirmed by location of a small scale monopolar near-IR reflection nebula at the base of the blueshifted lobe. A secon...
