The SSDC contribution to the improvement of knowledge by means of 3D data projections of minor bodies
Longobardo, Andrea; Palomba, Ernesto; Zinzi, Angelo +6 more
The latest developments of planetary exploration missions devoted to minor bodies required new solutions to correctly visualize and analyze data acquired over irregularly shaped bodies.
ASI Space Science Data Center (SSDC - ASI, formerly ASDC - ASI Science Data Center) worked on this task since early 2013, when started developing the web tool…Exploring the substellar population in the Hyades open cluster
Rebolo, R.; Lodieu, N.; Pérez-Garrido, A. +1 more
Aims: Our aim is to identify substellar members of the nearby Hyades open star cluster to determine the photometric and spectroscopic properties of brown dwarfs at moderately old ages and extend our knowledge of the substellar mass function of the cluster.
Methods: We cross-matched the 2MASS and WISE public catalogues and measured proper…
Far-infrared photometry of OJ 287 with the Herschel Space Observatory
Lähteenmäki, Anne; Tornikoski, Merja; Tammi, Joni +6 more
Context. The blazar OJ 287 has shown a ≈12 year quasi-periodicity over more than a century, in addition to the common properties of violent variability in all frequency ranges. It is the strongest known candidate to have a binary singularity in its central engine. Aim. We aim to better understand the different emission components by searching for …
AGB Candidates in the Field of γ Cas1
Enke, H.; Nesci, R.; Tuvikene, T. +4 more
We report the spectroscopic and photometric monitoring of a sample of 530 candidate AGB stars in a 5×5 degrees field, selected from the IPHAS catalog; historic light curves were derived from Asiago IR plates taken in the years 1965-1984. We found 10 Miras, 5 stars with long term trends, 3 semiregular and 3 irregular. Spectral types from CCD slit s…
High-velocity hot CO emission close to Sgr A*. Herschel/HIFI submillimeter spectral survey toward Sgr A*
Teyssier, D.; Cernicharo, J.; Gerin, M. +3 more
The properties of molecular gas, the fuel that forms stars, inside the cavity of the circumnuclear disk (CND) are not well constrained. We present results of a velocity-resolved submillimeter scan ( 480-1250 GHz) and [C II] 158 µm line observations carried out with Herschel/HIFI toward Sgr A*; these results are complemented by a 2…
HATS-59b,c: A Transiting Hot Jupiter and a Cold Massive Giant Planet around a Sun-like Star
Arriagada, P.; Butler, R. P.; Crane, J. D. +27 more
We report the first discovery of a multi-planetary system by the HATSouth network, HATS-59b,c, a planetary system with an inner transiting hot Jupiter and an outer cold massive giant planet, which was detected via radial velocity. The inner transiting planet, HATS-59b, is on an eccentric orbit with e=0.129+/- 0.049, orbiting a V=13.951+/- 0.030 ma…
The molecular H2 and stellar discs in the nuclear region of NGC 4258
Steiner, J. E.; Menezes, R. B.; da Silva, Patrícia
NGC 4258 is an SABbc Seyfert galaxy, located at a distance of 7.2 ± 0.3 Mpc. This object is well known by its nearly edge-on molecular nuclear disc, located between 0.16 and 0.28 pc from the nucleus, whose H2O maser emission allows a very precise measurement of the central supermassive black hole mass (M•(maser) = 3.78 ± 0.01…
Searching for new young stars in the Northern hemisphere: the Pisces moving group
Jeffries, R. D.; Binks, A. S.; Ward, J. L.
Using the kinematically unbiased technique described in Binks, Jeffries & Maxted (2015), we present optical spectra for a further 122 rapidly rotating (rotation periods <6 d), X-ray active FGK stars, selected from the SuperWASP survey. We identify 17 new examples of young, probably single stars with ages of <200 Myr and provide additiona…
The strength of ice-saturated extraterrestrial rock analogs
Seager, Sara; Atkinson, Jared; Durham, William B.
In situ resource utilization (ISRU) activities have been identified by the National Research Council as one of the most important scientific endeavors of the coming decade. The failure of the MUPUS-PEN experiment on Rosetta's Philae lander to penetrate the surface of comet 67P demands knowledge of the mechanical properties of extraterrestrial mate…
Kinematics of outer halo globular clusters: M 75 and NGC 6426
Hanke, Michael; Kacharov, Nikolay; Koch, Andreas
Globular clusters (GCs) and their dynamic interactions with the Galactic components provide an important insight into the structure and formation of the early Milky Way. We present a kinematic study of two outer halo GCs based on a combination of VLT/FORS2, VLT/FLAMES, and Magellan/MIKE low- and high-resolution spectroscopy of 32 and 27 member sta…
