Optical constraints on the coldest metal-poor population
Jerry Jun-Yan Zhang, Nicolas Lodieu, Eduardo L. Martín +10
The coldest metal-poor population made of T and Y dwarfs are archaeological tracers of our Galaxy because they are very old and have kept the pristine material. The optical propert…
Hints of auroral and magnetospheric polarized radio emission from the scallop-shell star 2MASS J050827292101444
Simranpreet Kaur, Daniele Viganò, Víctor J. S. Béjar +18
Scallop-shell stars, a recently discovered class of young M dwarfs, show complex optical light curves that are characterized by periodic dips as well as other features that are sta…
Isotopic abundance of carbon in the DLA towards QSO B1331+170
Dinko Milaković, John K. Webb, Paolo Molaro +19
Chemical evolution models predict a gradual build-up of C in the universe, based on empirical nuclear reaction rates and assumptions on the properties of stellar populations…
Probing the small scale structure of the Inter-Galactic Medium with ESPRESSO: spectroscopy of the lensed QSO UM673
Stefano Cristiani, Guido Cupani, Andrea Trost +20
The gravitationally lensed quasar J014516.6-094517 at z=2.719 has been observed with the ESPRESSO instrument at the ESO VLT to obtain high-fidelity spectra of the two images A and…
