This paper gives an overview of the CARMENES instrument and survey that will be carried out with it during first years operation. (Calar Alto high-Resolution search for M dwarfs Exoearths Near-infrared optical Echelle Spectrographs) is a next-generation radial-velocity under construction 3.5m telescope at Calar Observatory by consortium eleven Spanish German institutions. The scientific goal project conducting 600-night exoplanet targeting ~ 300 completed instrument. consists two separate...
We present a near-infrared spectroscopic survey of large area centered on the Cygnus OB2 association aimed at constraining its massive star contents. Our goal is to establish nearly complete list O-type members association, both examine recent claims based starcounts that suggest richer content than previously thought, and provide suitable database for further studies entire high-mass end one richest associations Galaxy. The target selection JHK photometry published in 2MASS all-sky survey....
SONYC -- Substellar Objects in Nearby Young Clusters is a survey program to investigate the frequency and properties of substellar objects nearby star-forming regions. We present new imaging spectroscopic conducted young (~1 Myr), (~200 pc) region Lupus 3. Deep optical near-infrared images were obtained with MOSAIC-II NEWFIRM at CTIO-4m telescope, covering ~1.4 sqdeg on sky. The i-band completeness limit 20.3 mag equivalent 0.009-0.02 MSun, for Av \leq 5. Photometry 11-12 yr baseline proper...
<i>Context. <i/>Most studies of the stellar and substellar populations star-forming regions rely on using signatures accretion, outflows, disks, or activity characterizing early stages evolution. However, these rapidly decay with time.<i>Aims. <i/>We present results a wide-area study population clouds in Lupus region. When combined 2MASS photometry, our data allow us to fit spectral energy distributions over 150 000 sources identify possible new members based their photospheric fluxes,...
Bluetongue is an infectious, non-contagious, arthropod-borne viral disease of ruminants caused by bluetongue virus (BTV), producing severe impacts on livestock. Historically, Southern Europe has suffered multiple incursions different BTV serotypes with serious consequences. In 2021, re-emerged in the Balearic Islands (Spain) after 16 years free disease, causing a large outbreak that mainly affected sheep, as well cattle and goats. A novel emerging strain serotype 4 (BTV-4) was identified via...
The mission discovered several hundred thousand long-period variables and measured parallaxes for many of them. These stars will allow us to study populations variable in the Milky Way, including asymptotic giant branch (AGB) stars. This paper describes identification counterparts a sample oxygen-rich AGB with OH maser emission as first step towards compilation general Catalogue Galactic With this catalogue, tests evolutionary models star population solar neighbourhood become feasible. We...
We present the results of a multiband survey for brown dwarfs in Chamaeleon I dark cloud with Wide Field Imager (WFI) camera at ESO/MPG 2.2-m telescope on La Silla (Chile). The has revealed substantial population this southern star-forming region. Candidates were selected from R, and Hα imaging observations. also observed two medium-band filters, M 855 915, spectral type determination. former filter covers wavelength range containing features characteristic M-dwarfs, while latter lies...
We present 27 new L subdwarfs and classify five of them as esdL 22 sdL. Our subdwarf candidates were selected with the UKIRT Infrared Deep Sky Survey Sloan Digital Survey. Spectroscopic follow-up was carried out primarily OSIRIS spectrograph on Gran Telescopio Canarias. Some these objects followed up X-shooter instrument Very Large Telescope. studied photometric properties population known using colour-spectral type diagrams colour-colour diagrams, by comparison dwarfs main-sequence stars,...
(abridged) We want to provide further evidence of the origin proposed stellar members Chamaeleon and identify interlopers from foreground \epsilon Cha \eta associations. To this aim, we compile lists spectroscopically confirmed I II, Cha, background objects in same line sight. Using Virtual Observatory tools, cross-match these with UCAC3 catalogue get proper motions objects. In vector point diagram, different moving groups, use information study membership candidate associations literature....
ESASky is a science-driven discovery portal to explore the multi-wavelength sky and visualize access multiple astronomical archive holdings. The tool web application that requires no prior knowledge of any missions involved gives users world-wide simplified highest-level science data products from space-based astronomy plus number ESA source catalogs. first public release features interfaces for visualization in wavelengths, query results summaries, observations catalog sources single...
Aims: By using kinematical information, we test the membership of new Lupus candidate members proposed by Cores to Disks (c2d) Spitzer Legacy Program program and a complementary optical survey. We also investigate relationship between proper motions (pm) other properties, in order get some clues about their formation early evolution. Methods: compiled list possible 1, 3, 4, together with all information on spectral types, disks, physical parameters. Using VO-tools, cross-matched this...
Context. Many star forming regions are known to have associated dispersed populations, whose members located away from current sites. Their origin is unclear, and any identification of the through relatively short-lived signatures youth can miss them.
We report on a multi-band survey for very low-mass stars and brown dwarfs in the Lupus 3 cloud with Wide Field Imager (WFI) at ESO/MPG 2.2m telescope La Silla Observatory (Chile). Our multiband optical photometry is combined available 2MASS JHK to identify 19 new young dwarf candidates as probable members of this star forming region. objects are mostly clustered around core. Stars have similar levels H-alpha emission, probably signature accretion. One object, candidate, exhibits...
We present the results of a deep optical survey in Corona Australis and Chamaeleon II star forming regions. Our photometry is combined with available near- mid-infrared to identify very low-mass candidate members these dark clouds. In our field, only one object exhibits clear H-alpha emission, but discrepancy between its near-infrared colours suggests that it might be foreground star. also two objects without emission could planetary mass II. Australis, we find ten stars three brown dwarf...
The Chamaeleon star-forming region has been extensively studied in the last decades. However, most studies have confined to densest parts of clouds. In a previous paper, we analysed kinematical properties spectroscopically confirmed population I and II We now report on search for new candidate members moving groups using available information from public databases catalogues. Our candidates were initially selected an area 3 deg around each cloud basis proper motions colours UCAC4 Catalog....
