Joint Analysis of Multicolor Photometry: A New Approach to Constrain the Nature of Multiple-star Systems Hosting Exoplanet Candidates
Miyakawa, Kohei; Hirano, Teruyuki; Sato, Bun'ei +2 more
We present a new method to assess the properties of transiting planet candidates by multicolor photometry. By analyzing multicolor transit/eclipse light curves and apparent magnitudes of the target in parallel, this method attempts to identify the nature of the system and provide a quantitative constraint on the properties of unresolved companion(…
In-flight verification of the engineering design data for the Energetic Particle Detector on board the ESA/NASA Solar Orbiter
Wimmer-Schweingruber, Robert F.; Elftmann, Robert; Rodríguez-Pacheco, Javier +25 more
This work presents an overview of the in-flight engineering data of the Energetic Particle Detector (EPD) instrument suite during its first year of operation. EPD is part of the in-situ scientific payload of the ESA/NASA Solar Orbiter mission which was launched in February 2020. After completion of its commissioning phase, Solar Orbiter started it…
The OTELO survey. Revealing a population of low-luminosity active star-forming galaxies at z ∼ 0.9
Barrufet, Laia; Gallego, Jesús; Sánchez-Portal, Miguel +16 more
Aims: We study a sample of Hβ emission line sources at z ∼ 0.9 to identify the star-forming galaxies sample and characterise them in terms of line luminosity, stellar mass, star formation rate, and morphology. The final aim is to obtain the Hβ luminosity function of the star-forming galaxies at this redshift.
Methods: We used the red tun…
The Atacama Cosmology Telescope: SZ-based masses and dust emission from IR-selected cluster candidates in the SHELA survey
Papovich, Casey; Finkelstein, Steven L.; Hilton, Matt +19 more
We examine the stacked thermal Sunyaev-Zel'dovich (SZ) signals for a sample of galaxy group and cluster candidates from the 24 deg2 infrared Spitzer-HETDEX Exploratory Large Area (SHELA) survey. We identify the objects in combination with optical data using the redMaPPer algorithm, and divide them into three richness bins (λ in 10-20, 2…
The Mars Orbiter for Resources, Ices, and Environments (MORIE) Science Goals and Instrument Trades in Radar, Imaging, and Spectroscopy
Murchie, Scott L.; Ehlmann, Bethany L.; Calvin, Wendy M. +9 more
The Mars Orbiter for Resources, Ices, and Environments (MORIE) was selected as one of NASA's 2019 Planetary Mission Concept Studies. The mission builds upon recent discoveries and current knowledge gaps linked to two primary scientific questions: (1) when did elements of the cryosphere form and how are ice deposits linked to current, recent, and a…
Searching for Saturn's X-rays during a rare Jupiter Magnetotail crossing using Chandra
Jackman, C. M.; Branduardi-Raymont, G.; Nichols, J. D. +6 more
Every 19 yr, Saturn passes through Jupiter's 'flapping' magnetotail. Here, we report Chandra X-ray observations of Saturn planned to coincide with this rare planetary alignment and to analyse Saturn's magnetospheric response when transitioning to this unique parameter space. We analyse three Director's Discretionary Time (DDT) observations from th…
Deciphering the 3D Orion Nebula. III. Structure on the NE Boundary of the Orion-S Embedded Molecular Cloud
Abel, N. P.; O'Dell, C. R.; Ferland, G. J.
We have extended the work of Papers I and II of this series to determine at a higher spatial resolution the properties of the embedded Orion-S Molecular Cloud that lies within the ionized cavity of the Orion Nebula and of the thin ionized layer that lies between the Cloud and the observer. This was done using existing and new [N II] (658.3 nm) and…
Morphological study of the nested planetary nebula Hubble 12
Zhang, Yong; Sadjadi, SeyedAbdolreza; Hsia, Chih-Hao +3 more
We present a visible-infrared imaging study of young planetary nebula (PN) Hubble 12 (Hb 12; PN G111.8-02.8) obtained with Hubble Space Telescope (HST) archival data and our own Canada-France-Hawaii Telescope (CFHT) measurements. Deep HST and CFHT observations of this nebula reveal three pairs of bipolar structures and an arc-shaped filament near …
MEGARA-GTC stellar spectral library - II. MEGASTAR first release
Mollá, M.; Cardiel, N.; Gil de Paz, A. +4 more
MEGARA is an optical integral field and multi-object fibre-based spectrograph for the 10.4 m Gran Telescopio CANARIAS that offers medium-to-high spectral resolutions (FWHM) of R ≃ 6000, 12 000, 20 000. Commissioned at the telescope in 2017, it started operation as a common-user instrument in 2018. We are creating an instrument-oriented empirical s…
An investigation of the causal relationship between sunspot groups and coronal mass ejections by determining source active regions
Wang, Haimin; Wang, Jason T. L.; Cavus, Huseyin +3 more
Although the source active regions of some coronal mass ejections (CMEs) were identified in CME catalogues, vast majority of CMEs do not have an identified source active region. We propose a method that uses a filtration process and machine learning to identify the sunspot groups associated with a large fraction of CMEs and compare the physical pa…
