Surface brightness–colour relations of Milky Way and Magellanic Clouds classical Cepheids based on Gaia magnitudes

Astronomy & Astrophysics
Context. Surface brightness–colour relations (SBCRs) are widely used to estimate the angular diameters of stars. In particular, they are employed in the Baade–Wesselink distance determination method, which relies on the comparison between the linear and ...

A Neutral Hydrogen Absorption Study of Cold Gas in the Outskirts of the Magellanic Clouds Using the GASKAP-H i Survey

The Astronomical Journal
Cold neutral hydrogen (H i ) is a crucial precursor for molecular gas formation and can be studied via H i absorption. This study investigates H i absorption in low column density regions of the Small and Large Magellanic Clouds (SMC and LMC) using the ...

Orbits of LMC/SMC with recent ground-based proper motions

EPJ Web of Conferences, 2012
In recent years, with new ground-based and HST measurements of proper motions of the Magellanic Clouds being published, a need of a reanalysis of possible orbital history has arisen.

VLT/UVES Observations of Interstellar Molecules and Diffuse Bands in the Magellanic Clouds

, 2006
We discuss the abundances of interstellar CH, CH+, and CN in the Magellanic Clouds (MC), derived from spectra of 7 SMC and 13 LMC stars obtained (mostly) with the VLT/UVES.

Distance scale calibration based on early-type binaries

EPJ Web of Conferences, 2017
Our main goal is to establish a firm empirical calibration of the surface brightness vs. (V-K) color relation for early type stars based on high quality spectroscopic and infrared observations of early-type detached eclipsing systems in the Large ...

Absolute Proper Motion of the Fornax Dwarf Spheroidal Galaxy from Photographic and HST WFPC2 Data

, 2004
We have measured the absolute proper motion of the Fornax dwarf spheroidal galaxy from a combination of photographic plate material and HST WFPC2 data that provide a time baseline of up to 50 years.

The Small Magellanic Cloud [PDF]

Symposium - International Astronomical Union, 1959
In 1957 a two-year photometric study of the Small Magellanic Cloud, sponsored by Indiana University and supported by the National Science Foundation was completed. Six region swere investigated. They are three on the edge of the SMC centered on conspicuous star clusters and three nearer the center.

Ages of Large Magellanic Cloud Star Clusters with Gemini Multi-Object Spectrograph Integrated Spectroscopy: Systematic Comparison of Available Tools

The Astronomical Journal
We present the first systematic analysis comparing the ages, reddening, and radial velocities of star clusters using two widely used tools: STARLIGHT and Analyzer of Spectra for Age Determination (A.S.A.D). Both tools utilize the full integrated spectrum
