Molecular Clouds in the Large and Small Magellanic Clouds

Large and Small Magellanic Clouds

We present period-luminosity relations for more than 3,200 red variable stars in the Small Magellanic Cloud observed in the second phase of the Optical Gravitational Lensing Experiment (OGLE-II). Periods of multiply-periodic light curve solutions combined with the single-epoch 2MASS JHKS magnitudes, reveal very similar distributions to those for the Large Magellanic Cloud in Paper I. The main f...

Depth estimation of the Large and Small Magellanic Clouds

Context. A systematic estimation of the line of sight depth in the disk and bar regions of the Large and Small Magellanic Clouds (LMC and SMC) using red clump stars is presented. Aims. We used the red clump stars from the photometric data of the Optical Gravitational Lensing Experiment (OGLE II) survey and the Magellanic Cloud Photometric Survey (MCPS) for both the Clouds to estimate the depth....

Molecular abundances in the Magellanic Clouds

The first definite discoveries of extragalactic deuterium are reported. DCO has been detected in three and DCN has been measured in one star-forming region of the Large Magellanic Cloud (LMC). While the HCO/DCO abundance ratios are found to be 19± 3, 24 ± 4, and 67 ± 18 for N113, N44BC and N159HW, respectively, a HCN/DCN abundance ratio of 23 ± 5 is obtained for N113. These results are consiste...

Molecular abundance variations in the Magellanic Clouds

We have observationally studied the effect of metallicity and far-ultraviolet (FUV) radiation on the physical conditions and the molecular abundances in interstellar clouds in the Small and the Large Magellanic Clouds (SMC and LMC, respectively). Spectral line emission from a number of molecules was observed in a sequence of clouds with positions in and between the 30 Doradus (30Dor) and the so...
