On 17 December 2019 the names of 112 sets of exoplanets and host stars named in the International Astronomical Union's NameExoWorlds campaigns were announced at a press conference in Paris. Within the framework of the International Astronomical Union's 100th anniversary (IAU100) commemorations, 112 countries organized national campaigns involving more than 780 000 people around the world, who proposed and selected the names for each exoplanet and its host stars. The planetary system...

Telescopio Nazionale Galileo presents: Mercury Transit 2019 Live 11 November 2019 Telescopio Nazionale Galileo presents an afternoon dedicated to Mercury the smallest planet of the Solar System, on the occasion of its transit. From 12:35 UT to 18:27 UT: streaming of the transit live from Roque de Los Muchachos From 12:15 UT to 16:15 UT: a Hangout talk given from the TNG Control Room When the inferior planets of the Solar System, Mercury and Venus, are projected onto the solar disc as...

Accretion of matter and ejection through jets and winds are the most important processes that characterize the T Tauri stage of low-mass stellar evolution. These are also the main mechanisms concurring to disperse the gas in circumstellar disks, so they affect the disk evolution and set the initial conditions for planet formation, ultimately determining the architecture of planetary systems. Such processes occur on spatial scales (fraction of au) that cannot be resolved by present...

CALL FOR PROPOSALS TNG and REMalso featuring NOT time AOT 41 (2020A) is now open for proposals. Applications for observing time for the periods   April 1st, 2020 - September 30th, 2020 are solicited and should be submitted byMonday, 18th November, 2019, 12:00 UT. The available time offered at TNG via INAF-TAC is 61 (sixty-one) nights in this call. This offer can be increased if not all the nights assigned to other calls will be effectively allocated by the respective TACs....

Using the HARPS-N spectrograph mounted at the Telescopio Nazionale Galileo, an international team of astronomers led by Dr. Oscar Barragán from the Department of Physics of the University of Oxford has measured for the first time the mass of a transiting planet in a young open cluster. The object -- K2-100b, a Neptune-sized planet transiting an active star in the Praesepe open cluster -- is bound to become a valuable target to test planetary evolution models and to study the effects of...

The unique combination of HARPS-N (High Accuracy Radial velocity Planet Searcher in North hemisphere) and GIANO-B echelle spectrographs at the Telescopio Nazionale Galileo (TNG), which together cover almost the full optical and NIR range out to the K band, is ideal to sample the luminous stellar populations of the the Milk Way thin disk over almost its entire extension, as seen from the Northern Hemisphere at a spectral resolution R>=50,000. We proposed a Large Program called the 'SPA -...

The Nobel Prize for Physics 2019 was awarded to James Peebles for his discoveries in the field of cosmology; Michel Mayor and Didier Queloz for the discovery of the first exoplanet in orbit around a solar-type star, 51 Pegasi. M. Mayor, Professor at the University of Geneva, and D. Queloz, Professor at the University of Cambridge (United Kingdom), discovered, in 1995, the first planet orbiting a star outside our Solar System: 51 Pegasi b. The exoplanet located at a distance of 50 light years...

The researchers of the Global Architecture of Planetary Systems (GAPS) project discovered a new effect induced on the radial velocity measurements by the iron in the atmosphere of an ultra-hot Jupiter. The team of researchers analyzed four transits of KELT-9 observed with the high-resolution spectrograph HARPS-N at the Telescopio Nazionale Galileo. They found that the precise radial velocities were not matching the theoretical Rossiter-McLaughlin effect predictions (Fig. 1, top panel). ...
