Red Giant stars in the Large Magellanic Cloud clusters
Based on observations collected at the European Southern Observatory, La Silla, Chile, using SOFI at the 3.5m NTT, within the observing programs 64.N-0038 and 68.D-0287
متن کاملThe Effective Temperatures and Physical Properties of Magellanic Cloud Red Supergiants: The Effects of Metallicity
We present moderate-resolution optical spectrophotometry of 36 red supergiants (RSGs) in the LMC and 39 RSGs in the SMC. Using the MARCS stellar atmosphere models to fit this spectrophotometry, we determine the reddenings, effective temperatures and other physical properties, such as bolometric luminosity and effective stellar radii, and compare these to stellar evolutionary models. Current add...
متن کاملK-Band Red Clump Distance to the Large Magellanic Cloud
The Hipparcos I-band calibration of horizontal-branch red clump giants as standard candles has lead to controversial results for the distance to the Large Magellanic Cloud (LMC). In an attempt to properly ascertain the corrections for interstellar extinction and clump age and metallicity, we analyze new multiwavelength luminosity functions of the LMC red clump. Our photometry dataset in the K-b...
متن کاملTwo Ring Nebulae around Blue Supergiants in the Large Magellanic Cloud
Ring nebulae are often found around massive stars such as Wolf-Rayet stars, OB and Of stars and Luminous Blue Variables (LBVs). In this paper we report on two ring nebulae around blue supergiants in the Large Magellanic Cloud. The star Sk−69 279 is classified as O9f and is surrounded by a closed shell with a diameter of 4.5 pc. Our echelle observations show an expansion velocity of 14 kms and a...
متن کاملLarge Magellanic Cloud
Formation of GMCs is one of the most crucial issues in galaxy evolution. I will compare CO and HI in the LMC in 3 dimensional space for the first time aiming at revealing the physical connection between GMCs and associated HI gas at a ∼ 40 pc scale. The present major findings are 1) [total CO intensity] ∝ [total HI intensity] for the 110 GMCs, and 2) the HI intensity tends to increase with the ...
