The sharpest optical images of the R136 cluster in the Large Magellanic Cloud are presented, allowing us for the first time to resolve members of the central core, including R136a1, the most-massive star known. These data were taken using the Gemini speckle imager Zorro in medium-band filters with effective wavelengths similar to BVRI achieving angular resolutions between 30–40 mas. All stars previously known in the literature, having V < 16 mag within the central 2″ × 2″, were recovered…

VLT/SINFONI time-resolved spectroscopy of the central, luminous, H-rich WN stars of R136★

ABSTRACT Using the Very Large Telescope’s Spectrograph for INtegral Field Observation in theNear-Infrared (VLT/SINFONI), we have obtained repeated AO-assisted, NIR spec-troscopy of the six central

VLT‐MAD observations of the core of 30 Doradus

We present H- and Ks-band imaging of three fields at the centre of 30 Doradus in the Large Magellanic Cloud, obtained as part of the Science Demonstration programme with the Multi-conjugate Adaptive

The R136 star cluster dissected with Hubble Space Telescope/STIS – II. Physical properties of the most massive stars in R136

We present an optical analysis of 55 members of R136, the central cluster in the Tarantula Nebula of the Large Magellanic Cloud. Our sample was observed with STIS aboard the Hubble Space Telescope,

The R136 star cluster hosts several stars whose individual masses greatly exceed the accepted 150 M⊙ stellar mass limit

Spectroscopic analyses of hydrogen-rich WN5‐6 stars within the young star clusters NGC 3603 and R136 are presented, using archival Hubble Space Telescope and Very Large Telescope spectroscopy, and

The emergence of super-canonical stars in R136-type starburst clusters

Among the most remarkable features of the stellar population of R136, the central, young, massive star cluster in the 30 Doradus complex of the Large Magellanic Cloud, are the single stars whose

The R136 star cluster dissected with Hubble Space Telescope/STIS. I. Far-ultraviolet spectroscopic census and the origin of He II λ1640 in young star clusters

We introduce a Hubble Space Telescope (HST)/Space Telescope Imaging Spectrograph (STIS) stellar census of R136a, the central ionizing star cluster of 30 Doradus. We present low resolution

A distance to the Large Magellanic Cloud that is precise to one per cent

A new calibration of the surface brightness–colour relation of eclipsing binary stars gives a distance to the Large Magellanic Cloud that is precise to one per cent.

An excess of massive stars in the local 30 Doradus starburst

The recent formation history and the initial mass function (IMF) of massive stars in 30 Doradus is determined on the basis of spectroscopic observations of 247 stars more massive than 15 solar masses, and the main episode of massive star formation began about 8 million years ago and seems to have declined in the last 1 My.

Rotating massive main-sequence stars - I. Grids of evolutionary models and isochrones

We present a dense grid of evolutionary tracks and isochrones of rotating massive main-sequence stars. We provide three grids with different initial compositions tailored to compare with early OB
