Time-Frequency Analysis of Superorbital Modulation of X-ray Binary SMC X-1 by Hilbert-Huang Transform
Time-Frequency Analysis Superorbital Modulation X-ray Binary SMC X-1 Hilbert-Huang Transform
2011/10/21
The high-mass X-ray binary (HMXB) SMC X-1 exhibits a superorbital modulation with a dramatically varying period ranging between ~40 d and ~60 d. This research studies the time-frequency properties of ...
Surveying the Agents of Galaxy Evolution in the Tidally-Stripped, Low Metallicity Small Magellanic Cloud (SAGE-SMC). I. Overview
Surveying Agents Galaxy Evolution Tidally-Stripped Small Magellanic Cloud
2011/10/13
The Small Magellanic Cloud (SMC) provides a unique laboratory for the study of the lifecycle of dust given its low metallicity (~1/5 solar) and relative proximity (~60 kpc). This motivated the SAGE-SM...
SMC SMP 24: A newly radio-detected planetary nebula in the small magellanic cloud
SMC SMP 24 newly radio-detected planetary nebula
2011/1/10
In this paper we report new radio-continuum detection of an extragalactic PN: SMC SMP 24. We show the radio-continuum image of this PN and present the measured radio data. The newly reduced radio obse...
Orbital Period Determinations for Four SMC Be/X-ray Binaries
Orbital Period Determinations SMC Be/X-ray Binaries
2011/1/11
We present an optical and X-ray study of four Be/X-ray binaries located in the Small Magellanic Cloud (SMC). OGLE I-band data of up to 11 years of semi-continuous monitoring has been analysed for SMC ...
New limb-darkening coefficients and synthetic photometry for model-atmosphere grids at Galactic, LMC, and SMC abundances
New limb-darkening coefficients synthetic photometry for model-atmosphere grids SMC abundances
2010/11/15
New grids of Atlas9 models have been calculated using revised convection parame-ters and updated opacity-distribution functions, for chemical compositions intended to be representative of solar, [M/H]...
Light Curve Solutions of Eclipsing Binaries in SMC
eclipsing binaries light curves modeling Small Magellanic Cloud global parameters
2010/11/12
We propose a procedure for light-curve solution of eclipsing bi-nary stars in the Small Magellanic Cloud for which photometric data have been obtained in the framework of the OGLE project as well as w...
Mass loss rates inferred from mid-IR color excesses of LMC and SMC O stars
Solar and Stellar Astrophysics (astro-ph.SR) Galaxy Astrophysics (astro-ph.GA)
2011/1/6
We use a combination of VJHK and Spitzer} [3.6], [5.8] and [8.0] photometry, to determine IR excesses in a sample of LMC and SMC O stars.
