A review of low-energy transfers

DOI: 10.1007/s10509-018-3461-4 Bibcode: 2018Ap&SS.363..253D

Dutt, Pooja

Low-energy transfers (LET) for lunar and interplanetary missions has received immense attention of the scientific community during the last few decades as its importance was understood by the success of JAXA's Hiten, ESA's SMART-1, NASA's GRAIL and ARTHEMIS missions, and several proposals, like the BepiColombo, Multi-Moon Orbiter and Europa Orbite…

Identification of V735 Sgr as an Active Herbig Ae/Be Object

DOI: 10.32023/0001-5237/68.3.5 Bibcode: 2018AcA....68..259P

Udalski, A.; Pietrukowicz, P.; Angeloni, R. +1 more

V735 Sgr was known as an enigmatic star with rapid brightness variations. Long-term OGLE photometry, brightness measurements in infrared bands, and recently obtained moderate resolution spectrum from the 6.5-m Magellan telescope show that this star is an active young stellar object of Herbig Ae/Be type.

Spectroscopic Investigations of Galactic Clusters with Associated Cepheid Variables. II. NGC 5662 and V Cen

DOI: 10.18524/1810-4215.2018.31.145381 Bibcode: 2018OAP....31..117U

Kniazev, A. Yu.; Miroshnichenko, A. S.; Mishenina, T. V. +4 more

We present the results of a spectroscopic and photometric investigation of 15 objects from the open cluster NGC 5662, which contains the Cepheid V Cen. Besides the Cepheid, we studied one G-supergiant, two K-giants, four B-giants, and seven main sequence stars. Radial velocities (RV), v sin i, T_eff, log g, and [Fe/H] were determined usi…

A key piece in the exoplanet puzzle

DOI: 10.1038/d41586-018-07328-7 Bibcode: 2018Natur.563..329D

Díaz, Rodrigo F.

The detection of a low-mass exoplanet on a relatively wide orbit has implications for models of planetary formation and evolution, and could open the door to a new era of exoplanet characterization.

The NGC 7742 star cluster luminosity function: a population analysis revisited

DOI: 10.1088/1674-4527/18/2/13 Bibcode: 2018RAA....18...13D

de Grijs, Richard; Ma, Chao

We re-examine the properties of the star cluster population in the circumnuclear starburst ring in the face-on spiral galaxy NGC 7742, whose young cluster mass function has been reported to exhibit significant deviations from the canonical power law. We base our reassessment on the clusters’ luminosities (an observational quantity) rather than the…

Revised coordinates of 3 variable stars in Cygnus

DOI: 10.22444/IBVS.6242 Bibcode: 2018IBVS.6242....1N

Nesci, R.

The identification of the variable stars published on IBVS 1302 has ben checked on the basis of the original (unpublished) finding charts. For 3 stars significant differences were found and are reported here to allow an easier recovery by automatic cross-check procedures using digital catalogs. Some data from the recent Gaia DR2 catalog are also g…
