A near-IR survey is conducted in order to penetrate the dust of the Galactic plane through the K window and study the flux from Rayleigh-Jeans tail emission in...
The region around the Herbig Ae/Be star LKH-alpha198 was imaged at 10 micrometer with the CAMIRAS camera at the Canada-France-Hawaii Telescope and the Nordic...
A Multi-epoch, Multiwavelength Study of the Classical FUor V1515 Cyg Approaching Quiescence
Historically, FU Orionis-type stars are low-mass, pre-main-sequence stars. The members of this class experience powerful accretion outbursts and remain in an...
A semi-empirical absolute flux calibration in the near infrared: Direct stellar diameters vs. IRFM determinations
A new semi-empirical method to derive the absolute flux calibration in the near infrared (J,K,L and L' bands) is proposed. The method consists of the...
A survey of faint, near-infrared sources towards the centre of the Galaxy
The authors present the results of a survey made at 1.65 μm (H) and 2.2 μm (K) in 15 small areas on the galactic equator between l = 0° and l = 10°. 775...
JWST, despite not being designed to observe astrophysical phenomena that vary on rapid timescales, can be an unparalleled tool for such studies. If timing...
Circumstellar matter around the RS CVn system II Peg
The RS CVn noneclipsing system II Peg has been observed in the J, H, K, L, and M infrared bands along a complete period. The shape of the light curve shows an...
Confirmation of Color-dependent Centroid Shift Measured After 1.8 Years with HST
We measured the precise masses of the host and planet in the OGLE-2003-BLG-235 system, when the lens and source were resolving, with 2018 Keck high resolution...
Cooled instrumentation for infrared astronomical investigations from space
A brief review is presented of infrared astronomical instrumentation which has been proposed or accepted for observations from space platforms. Some stress is...
