Highlights from ILEWG LUNEX EuroMoonMars Earth Space Innovation, ArtMoonMars, Space Renaissance & EuroSpaceHub
Foing, Bernard H.
EuroMoonMars is an ILEWG/LUNEX programme in collaboration with space agencies, academia, universities and research institutions and industries. The programme includes research activities for data analysis, instruments tests and development, field tests in MoonMars analogue, pilot projects, training and hands-on workshops, and outreach activities. …
The Precise Individual Masses and Theoretical Stability and Habitability of some Single-lined Spectroscopic Binaries
Abushattal, A. A.; Kraishan, A. F.; Algnamat, B. S. +1 more
Over the past few decades, some Spectroscopic Binaries (SBs) have been resolved using high-resolution techniques. Astrophysics is interested in this subject because we can obtain the mass of each component. By combining a visual solution with a complimentary one, such as the spectroscopic orbit or Edward method, we can determine the individual mas…
X-ray hot spots in the eastern ear of the supernova remnant W 50 and the microquasar SS 433 system
Katsuda, Satoru; Sato, Toshiki; Uchiyama, Hideki +10 more
We examined the X-ray and radio spatial structure at the eastern ear of the W 50/SS 433 system to clarify a characteristic feature of the termination region of the SS 433 jet, and found that a hot spot ahead of the filament structure, which is considered to be a terminal shock of the SS 433 eastern jet, is clearly different from a single point sou…
Photometric Study of the Open Cluster NGC 225
Carraro, G.; Ikonnikova, N. P.; Yalyalieva, L. N. +2 more
—NGC 225 is a young moderately populated cluster with discrepant age, distance, and color excess estimates reported by different authors. We combine our photometry with the data from large surveys (2MASS, WISE, Pan-STARRS) to derive the parameters of NGC 225 and study the extinction law in the near infrared in the direction of the cluster. We use …
Formation and Immediate Deformation of a Small Filament Through Intermittent Magnetic Interactions
Zhang, Liang; Chen, Yao; Zheng, Ruisheng +4 more
It is generally believed that filament formation involves a process of the accumulation of magnetic energy. However, in this article, we discuss the idea that filaments will not erupt and will only deform when the stored magnetic energy is released gradually. Combining high-quality observations from SolarDynamicsObservatory and other instruments, …
Charge-injection Device Imaging of Sirius with Contrast Ratios Greater than 1:26 Million
Sawant, Sailee M.; Batcheldor, Daniel
The intrinsic nature of many astronomical objects, such as binary and multiple systems, exoplanets, circumstellar and debris disks, and quasar host galaxies, introduces challenging requirements for observational instrumentation and techniques. In each case, we encounter situations where the light from bright sources hampers our ability to detect s…
Method of evaluation of the most probable mean radial velocities of open star clusters
Kovaleva, D. A.; Kalinkin, A. D.; Kondratev, N. E. +1 more
In this article the method of self-consistent estimate of star clusters' average radial velocity by kinematic parameters was proposed. The method is based on convergent point method of probable cluster members determination. By modelling the method validation was held and properties of received estimate depending on a number of cluster parameters …
Studying young stellar populations in G345.5+1.5 molecular cloud
Baume, G.; Borissova, J.; Ramirez Alegria, S.
Using different sky surveys, we studied IRAS sources and embedded clusters located in the G345.5+1.5 region. Our analysis comprises multi-wavelength (optical to radio) data, exploited using various methods: photometry, near-infrared spectroscopy for ten stars in the embedded cluster DBS-114, and astrometry. We estimated the main parameters of the …
First Global Lunar Magnesium and Aluminum Abundance Maps Derived Using Chandrayaan-1 and Chandrayaan-2 Data
Wöhler, C.; Bhatt, M.; Narendranath, S. +3 more
CLASS-derived abundances of Mg and Al were used as ground truth and an empirical multivariate linear regression model developed for M3 global coverage.
