Corrigendum to "Photometrically-corrected global infrared mosaics of Enceladus: New implications for its spectral diversity and geological activity" [Icarus 349 (2020) 113848]
Le Mouélic, S.; Rodriguez, S.; Sotin, C. +4 more
The authors regret that the longitude grid in Figures. 9 and 11 was wrongly shifted by 180° in the original manuscript. We provide below the correct versions of Figures. 9 and 11.
Identifying Periodic Variable Stars and Eclipsing Binary Systems with Long-term Las Cumbres Observatory Photometric Monitoring of ZTF J0139+5245
Vanderbosch, Zachary P.; Montgomery, Michael H.; Sanghi, Aniket
We present the results of our search for variable stars using the long-term Las Cumbres Observatory (LCO) monitoring of white dwarf ZTF J0139+5245 with the two 1.0 m telescope nodes located at McDonald Observatory using the Sinistro imaging instrument. In this search, we find 38 variable sources, of which 27 are newly discovered or newly classifie…
Analysis of Study Results of the Polar Coronal Hole on the Sun According to Observations in the Microwave Wavelength Range
Golubchina, O. A.
An overview is presented of the main results of the study of the polar coronal hole over the North pole of the Sun based on observations of the solar eclipse on March 29, 2006, using the RATAN-600 radio telescope in a wide cm-range of wavelengths (1.03, 1.38, 2.7, 6.2, 13.0, 30.7 cm) along with observational and theoretical data about the properti…
A joint occultation and speckle investigation of the binary star TYC 1947-290-1 and of the asteroid (87) Sylvia
Richichi, A.; Dyachenko, V.; Obolentseva, M. +4 more
We report on the occultation of the star TYC 1947-290-1 by the asteroid (87) Sylvia. While asteroidal occultations occurring at fixed professional-level locations are relatively rare and are only recently starting to be observed with sufficiently high time resolution and sensitivity, they have the capability to measure sub-milliarcsecond angular d…
Model-driven environment for configuration control and deployment of on-board satellite software
Carrasco, Alberto; Martínez, Agustín; Sánchez, Sebastián +3 more
This paper describes a model-driven environment for configuration control and deployment of on-board satellite software. The solution enables platform-aware software development through the use of modelling artefacts provided by a framework called MICOBS. The paper describes the proposed platform model, as well as the supporting models needed to c…
The Energy Conversion Rate of an Active Region Transient Brightening Estimated by Hinode Spectroscopic Observations
Imada, Shinsuke; Kawai, Toshiki
We statistically estimate the conversion rate of the energy released during an active region transient brightening to Doppler motion and thermal and nonthermal energies. We used two types of data sets for the energy estimation and detection of transient brightenings. One includes spectroscopic images of Fe XIV, Fe XV, and Fe XVI lines observed by …
Photometric Variability of the Pre-main-sequence Stars toward the Sh 2-190 Region
Matsunaga, N.; Sharma, Saurabh; Panwar, Neelam +7 more
We present the results from our time-series imaging data taken with the 1.3 m Devasthal fast optical telescope and 0.81 m Tenagara telescope in V, Rc, and Ic bands covering an area of ~18'4 × 18'4 toward the star-forming region Sh 2-190. This photometric data helped us to explore the nature of the variability of pre-main-sequ…
Impacts of the PAH size and the radiation intensity on the IR features of illuminated dust within the reflection nebulae
Gadallah, Kamel A. K.; Ali, Abdallah A. M.
Interstellar dust grains are illuminated in the reflection nebulae. Under conditions of the PAH size and the intensity of the interstellar radiation field, we follow their impact on the PAH aromatic infrared bands using the numerical DustEM code. For a dust model consisting of PAH, amorphous C and amorphous silicate, the PAH size varies in a range…
X-ray analysis of the Planck-detected triplet-cluster system PLCK G334.8-38
Pointecouteau, Etienne; Douspis, Marian; Aghanim, Nabila +2 more
We conducted an X-ray analysis of one of the two Planck-detected triplet-cluster systems, PLCK G334.8-38.0, with a ∼100 ks deep XMM-Newton data. We find that the system has a redshift of z = 0.37 ± 0.01 but the precision of the X-ray spectroscopy for two members is too low to rule out a projected triplet system, demanding optical spectroscopy for …
Extensive glaciation in the Erebus Montes region of Mars
Sinha, Rishitosh K.; Ray, Dwijesh
Lobate debris apron (LDA) in the Mars' mid-latitudes substantiate extensive glaciation during the Late Amazonian. Detailed investigation of these landforms is imperative because different areas distributed at different latitudes, distinct geologic settings and varied regional topography may have responded to climate in different ways. In this stud…
