Analysis of exoplanetary system WASP-118
Fedurco, M.; Vaňko, M.; Parimucha, Š. +1 more
We present a new study of a recently discovered exoplanetary system WASP-118. The system consists of an F-type star and a close-in giant planet (an inflated hot Jupiter). Using Kepler-K2 observations, we re-determined the orbital and physical parameters of the system. Our results are in good agreement with the values published in the literature. T…

This article was temporarily removed from online publication in November 2018 after the article was accepted. The temporary removal was to coordinate a press release with the online publication of the article. There were no errors or problems with the content of the article.
Zooming out: what a broader view is telling us about stellar and substellar conglomerates
Peña Ramírez, K.
Measuring the distributions of ages and masses of low-mass stars and substellar sources in different young environments requires a thorough census of this specific population. Typically, studies have searched for defined conglomerate members using signatures of youth (variability, emission lines, infrared (IR) excess emission, X-ray emission), pro…
From Mars Express to ExoMars: Two missions working together around Mars
López-Valverde, M. A.; Cardesín-Moinelo, A.; Mars Express Centre +1 more
This year 2018 is very important for the Mars scientific community in Europe since for the first time two missions of the European Space Agency coincide around the orbit of Mars, opening a great opportunity for collaboration to improve our understanding of our neighbour planet. The Mars Express mission is fully operational and has been providing g…
Remarks about the data processing of the Relaxation Probe on the Huygens experiment
Molina-Cuberos, G. J.; Godard, R.
On January 14, 2005, the Relaxation Probe (RP) on the Huygens experiment measured the electrical conductivity in the lower atmosphere of Titan, the largest Saturnian satellite, from 140 km to 40 km of altitude. The Huygens experiment provided a unique opportunity to compare results from the Mutual Impedance Probe (MIP) with the Relaxation Probe (R…
A New Variable in the Field of WD1145+017
Serebryanskiy, A.
Revisit of the CCD archive obtained during long-time monitoring of the white dwarf WD1145+015 at Tien-Shan Observatory revealed a new variable star, identified as Gaia DR2 3796400796427214848. It was inferred that this star is of spectral type G7V-G8V. The amount of photometric data allows performing detailed analysis of this target, revealing its…
Elemental abundances of RGB and red clump stars in the Kepler field
Wang, L.; Zhao, G.; Takeda, Y. +2 more
The helium flash is a key point in the evolution process of stars that have evolved off the main sequence. However, chemical abundance differences in the stellar photosphere before and after this step are poorly investigated, mainly because of the degeneracy of red giant branch (RGB) and red clump stars (RC) in the Hertzsprung-Russell (HR) diagram…
The HH34 Jet/Counterjet System at 1.5 and 4.5µm
Raga, A. C.; Noriega-Crespo, A.; Reipurth, B.
We present a (previously unpublished) 1.5 µm archival HST image of the HH 34 Herbig-Haro jet, in which the northern counterjet is seen at an unprecedented angular resolution of ≈0.1" (this counterjet had only been imaged previously at lower resolution with Spitzer). The jet/counterjet structure observed in this image shows evidence of low-am…
XMM-Newton and Fermi/LAT view on the supernova remnant 3C434.1
Santangelo, A.; Pühlhofer, G.; Sasaki, M. +3 more
We report on XMM-Newton observations of the supernova remnant (SNR) 3C434.1 (G94.0+1.0), the first in X-rays since the ROSAT era. Our analysis confirms the thermal origin of the observed extended X-ray emission, whose morphology appears more complex than previously reported. In particular, part of the shell shows a significantly harder spectrum wh…
