Refining the Masses and Radii of the Star Kepler-33 and its Five Transiting Planets
Lissauer, Jack J.; Jontof-Hutter, Daniel; Sikora, James +1 more
Kepler-33 hosts five validated transiting planets ranging in period from 5 to 41 days. The planets are in nearly coplanar orbits and exhibit remarkably similar (appropriately scaled) transit durations indicative of similar impact parameters. The outer three planets have a radius of 3.5 ≲ R p/R ⊕ ≲ 4.7 and are closely packed d…
Indian Planetary Missions and Science
Bhardwaj, Anil
The planetary exploration program in India started in the new millennium with the launch of Chandrayaan-1 orbiter mission to the Moon in 2008, which was a highly successful mission since it discovered water on the Moon. The next Indian planetary mission was to Mars: the Mars Orbiter Mission (MOM), launched in November 2013 and arriving on Mars in …
Red giant branch bump brightness in 7 metal-poor globular clusters obtained with GAIA DR2
Nie, Jundan; Wu, Tao; Pietrinferni, Adriano +10 more
The identification of the red giant branch bump brightness in metal-poor globular clusters is important for low-mass stellar evolution. The release of Gaia DR2 prompted us to revisit the red giant branch bump (RGBB) in galactic globular clusters. We apply a popular nonparametric density estimation approach, kernel density estimation (KDE), to expl…
New late-type stars found in the BAO Plate Archive
Kostandyan, G. R.; Abrahamyan, H. V.; Paronyan, G. M. +1 more
The BAO Plate Archive low-resolution spectral plate centered \alpha = +04h; \delta = +240 is analyzed to find new late-type stars. 25 new late-type stars have been detected. We have performed cross-correlations with GAIA DR3, USNO-B1.0, 2MASS, AllWISE, IRAS PSC/FSC, AKARI and SDSS. For new detected objects, we present luminosity classes estimated …
Retrieval of Lunar Surface Temperature and Spectral Emissivity in 3-5 µm Range from Chandrayaan-2 IIRS Observations
Bhattacharya, S.; Ojha, S. P.; Vikram, K. V. N. G.
Algorithm for the retrieval of lunar surface temperature and emissivity is presented in this study.
Description and Application of the Surfing Effect
Nucita, Achille A.; De Paolis, Francesco; Maiorano, Michele
The standard technique for very low-frequency gravitational wave detection is mainly based on searching for a specific spatial correlation in the variation of the times of arrival of the radio pulses emitted by millisecond pulsars with respect to a timing model. This spatial correlation, which in the case of the gravitational wave background must …
Joint Cluster/Ground-Based Studies in the First 20 Years of the Cluster Mission
Fear, R. C.
Ground-based facilities make an important contribution to our understanding of the magnetospheric system. Coordination with ground-based facilities has been embedded within the Cluster mission since before launch, and this has given rise to a large number of studies which have exploited data from both Cluster and one or more of the diverse range o…
The Extragalactic Population of Accreting Neutron Stars and the Ultraluminous X-ray Sources Paradigm: from ULTraS to PULSULTraS
Salvaterra, R.; Tiengo, A.; de Luca, A. +11 more
The unambiguous identification of the nature of a neutron star in X-rays is achieved through the detection of coherent signals reflecting the spin period of the compact object. The search for coherent signals in the whole XMM-Newton source catalog was one of the main aims of the EU/FP7-funded project EXTraS (active in 2014-2016). The ULTraS and PU…
Spectral Unmixing and Abundance Estimation of Different Pyroxene Species Using IIRS Chandrayaan-2 Hyperspectral Imagery
Bhattacharya, S.; Kumar, A.; Misra, A. +6 more
Chandrayaan-2 IIRS was used to determine lunar minerals and their abundance near Taurus-Littrow valley consisting of Gardner Crater using linear mixing model.
