Galactic extinction laws: II. Hidden in plain sight, a new interstellar absorption band at 7700 Å broader than any known DIB
J. Maíz Apellániz, R. H. Barbá, J. A. Caballero +2
We have detected a broad interstellar absorption band centred close to 7700 Å and with a FWHM of 176.63.9 Å. This is the first such absorption band detected in the optical ran…
Studying star-forming processes at core and clump scales: the case of the young stellar object G29.862-0.0044
M. B. Areal, S. Paron, C. Fariña +3
Massive molecular clumps fragment into cores where star formation takes place, hence star-forming studies should be done at different spatial scales. Using near-IR data obtained wi…
Physical characterization of 2020 AV2, the first known asteroid orbiting inside Venus orbit
M. Popescu, J. de León, C. de la Fuente Marcos +8
The first known asteroid with the orbit inside that of Venus is 2020~AV. This may be the largest member of a new population of small bodies with the aphelion smaller than 0.7…
Three generations of stars: a possible case of triggered star formation
M. B. Areal, A. Buccino, S. Paron +2
Evidence for triggered star formation linking three generations of stars is difficult to assemble, as it requires convincingly associating evolved massive stars with Hii regions th…
