Adaptive Optics Photometry and Astrometry of Binary Stars. II. A Multiplicity Survey of B Stars [PDF]

open access: green, 2007
We carried out a search for companions to B stars using the adaptive optics system of the Advanced Electro-Optical System 3.6 m telescope. We observed 70 B stars in the I band, finding 16 companions, 10 of which are newly discovered companions.

The sharpest view on the high-mass star-forming region S255IR. Near infrared adaptive optics imaging of the outbursting source NIRS3 [PDF]

open access: yesAstronomy & Astrophysics, 2023
Massive stars have an impact on their surroundings from early in their formation until the end of their lives. However, very little is known about their formation.

Accurate Photometry of Saturated Stars Using the Point-spread-function Wing Technique with Spitzer [PDF]

open access: yesAstronomical Journal, 2021
We report Spitzer 3.6 and 4.5 μm photometry of 11 bright stars relative to Sirius, exploiting the unique optical stability of the Spitzer Space Telescope point-spread function (PSF).

High-contrast and resolution near-infrared photometry of the core of R136 [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2021
We present the sharpest and deepest near-infrared photometric analysis of the core of R136, a newly formed massive star cluster at the centre of the 30 Doradus star-forming region in the Large Magellanic Cloud.
