Very Large Telescope Observations of Interstellar Comet 3I/ATLAS. II. From Quiescence to Glow: Dramatic Rise of Ni i Emission and Incipient CN Outgassing at Large Heliocentric Distances*
Rohan Rahatgaonkar, Juan Pablo Carvajal, Thomas H. Puzia +25
We report VLT spectroscopy of the interstellar comet 3I/ATLAS (C/2025~N1) from to ~au using X-shooter (300--550\,nm, ) and UVES (opt…
Apsidal motion in the massive binary HD152248
S. Rosu, G. Rauw, K. E. Conroy +3
The eccentric massive binary HD152248 (also known as V1007 Sco), which hosts two O7.5 III-II(f) stars, is the most emblematic eclipsing O-star binary in the very young and rich ope…
Stellar parameters for TRAPPIST-1
Valerie Van Grootel, Catarina S. Fernandes, Michaël Gillon +10
TRAPPIST-1 is an ultracool dwarf star transited by seven Earth-sized planets, for which thorough characterization of atmospheric properties, surface conditions encompassing habitab…
Observational signatures of past mass-exchange episodes in massive binaries: The case of LSS 3074
F. Raucq, E. Gosset, G. Rauw +4
The role of mass and momentum exchanges in close massive binaries is very important in the subsequent evolution of the components. Such exchanges produce several observational sign…
WISE J072003.20-084651.2: An Old and Active M9.5 + T5 Spectral Binary 6 pc from the Sun
Adam J. Burgasser, Michael Gillon, Carl Melis +8
[Abridged] We report observations of the recently discovered, nearby late-M dwarf WISE J072003.20-084651.2. Astrometric measurements obtained with TRAPPIST improve the distance mea…
Investigation of the stellar content in the western part of the Carina nebula
Brajesh Kumar, Saurabh Sharma, Jean Manfroid +4
We obtained deep H photometric data of the field situated to the west of the main Carina nebula and centered on WR~22. Medium-resolution optical spectroscopy of a subsam…
