Lithium in the Hyades L5 brown dwarf 2MASSJ04183483+2131275. Lodieu N., Rebolo R., Perez-Garrido A. <Astron. Astrophys. 615, L12 (2018)> =2018A&A...615L..12L (SIMBAD/NED BibCode)
ADC_Keywords: Stars, dwarfs; Stars, M-type ; Spectra, optical Keywords: stars: brown dwarfs - Hyades - techniques: spectroscopic Abstract: We used the 10.4-m Gran Telescopio Canarias (GTC) with its low-dispersion optical spectrograph to obtain 10 spectra of 2277s each covering the range 6300-10300 Angstroms with a resolving power of R∼500 for the Hyades brown dwarf 2MASSJ04183483+2131275. We detect lithium in absorption and Halpha in emission in this combined spectrum. Description: Low-resolution optical spectra of 2MASSJ04183483+2131275 obtained with the OSIRIS instrument mounted on the Gran Telescopio de Canarias (GTC; grating R1000R, slit=1.2 arcsec) at Observatorio del Roque de los Muchachos (La Palma, Spain) over several nights between 23 January and 28 February 2017 as part of programme GTC77-16B (PI Perez-Garrido).
