  • From the margins to the mainstream: Nobel celebrates exoplanets! 
    Puravankara, Manoj; Banyal, R. K; Narang, Mayank (Indian Physics Association, 2019-12)
    This year’s Physics Nobel Prize was jointly awarded to three scientists. Phillip James Peebles from Princeton University, USA, received one half of the prize for his seminal work on physical cosmology, and other half was ...
  • Fullerenes in the circumstellar medium of Herbig Ae/Be stars: insights from the Spitzer mid-infrared spectral catalog 
    Arun, R; Mathew, Blesson; Manoj, P; Maheswar, G; Shridharan, B; Kartha, Sreeja S; Narang, Mayank (Oxford University Press on behalf of Royal Astronomical Society, 2023-08)
    This study presents the largest mid-infrared spectral catalogue of Herbig Ae/Be stars to date, containing the Spitzer Infrared Spectrograph spectra of 126 stars. Based on the catalogue analysis, two prominent infrared ...
  • Galactic Chemical Evolution of Exoplanet Hosting Stars: Are High-mass Planetary Systems Young? 
    Swastik, C; Banyal, R. K; Narang, Mayank; Manoj, P; Sivarani, T; Rajaguru, S. P; Athira Unni; Banerjee, Bihan (American Astronomical Society, 2022-08-01)
    The imprints of stellar nucleosynthesis and chemical evolution of the galaxy can be seen in different stellar populations, with older generation stars showing higher α-element abundances and the later generations ...
  • Host star metallicity of directly imaged wide-orbit planets: implications for planet formation 
    Swastik, C; Banyal, R. K; Narang, Mayank; Manoj, P; Sivarani, T; Reddy, B. E; Rajaguru, S. P (IOP Publishing, 2021-03-01)
    Directly imaged planets (DIPs) are self-luminous companions of pre-main-sequence and young main-sequence stars. They reside in wider orbits (~tens to thousands of astronomical units) and generally are more massive compared ...
  • Identifying the population of T-Tauri stars in Taurus: UV–optical synergy 
    Nayak, Prasanta K; Narang, Mayank; Puravankara, Manoj; Tyagi, Himanshu; Banerjee, Bihan; Sharma, Saurabh; Pandey, Rakesh; Surya, Arun; Mathew, Blesson; Arun, R; Ujjwal, K; Kartha, Sreeja S (Indian Academy of Sciences, 2023-12)
    With the third data release of the Gaia mission, GaiaDR3with its precise photometry and astrometry, it is now possible to study the behavior of stars at a scale never seen before. In this paper, we developed new criteria ...
  • Properties and Occurrence Rates for Kepler Exoplanet Candidates as a Function of Host Star Metallicity from the DR25 Catalog 
    Narang, Mayank; Manoj, P; Furlan, E; Mordasini, C; Henning, Thomas; Mathew, Blesson; Banyal, R. K; Sivarani, T (IOP Publishing, 2018-11)
    Correlations between the occurrence rate of exoplanets and their host star properties provide important clues about the planet formation process. We studied the dependence of the observed properties of exoplanets (radius, ...
  • Radio-loud Exoplanet-exomoon Survey: GMRT Search for Electron Cyclotron Maser Emission 
    Narang, Mayank; Oza, Apurva V; Hakim, Kaustubh; Manoj, P; Banyal, R. K; Thorngren, Daniel P (American Astronomical Society, 2023-01-01)
    We conducted the first dedicated search for signatures of exoplanet–exomoon interactions using the Giant Metrewave Radio Telescope (GMRT) as part of the radio-loud exoplanet-exomoon survey. Due to stellar tidal heating, ...
  • uGMRT observations of the hot-Saturn WASP-69b: Radio-Loud Exoplanet–Exomoon Survey II (RLEES II) 
    Narang, Mayank; Oza, Apurva V; Hakim, Kaustubh; Manoj, P; Tyagi, Himanshu; Banerjee, Bihan; Surya, Arun; Nayak, Prasanta K; Banyal, R. K; Thorngren, Daniel P (Oxford University Press on behalf of Royal Astronomical Society, 2023-06)
    Exomoons have so far eluded ongoing searches. Several studies have exploited transit and transit timing variations and highresolution spectroscopy to identify potential exomoon candidates. One method of detecting and ...
