    To understand the nature of SiO emission, we conducted ACA observations of the SiO (2-1) lines toward 146 massive starforming regions, as part of the ALMA Three-millimeter Observations of Massive Star-forming regions (ATOMS) ...
  • Evidence of high-mass star formation through multiscale mass accretion in hub-filament-system clouds

    We present a statisticalstudy of a sample of 17 hub-filament-system (HFS) clouds of high-massstar formation using high-angular resolution (∼1–2 arcsec) ALMA 1.3 and 3 mm continuum data. The sample includes eight infrared ...
  • p-capture reaction cycles in rotating massive stars and their impact on elemental abundances in globular cluster stars: A case study of O, Na and Al 
    Mahanta, Upakul; Goswami, A; Duorah, H. L; Duorah, K (IOP Publishing, 2017-08)
    Elemental abundance patterns of globular cluster stars can provide important clues for understanding cluster formation and early chemical evolution. The origin of the abundance patterns, however, still remains poorly ...
  • Spectral energy distributions and age estimates of 40 massive young stellar objects 
    Tanti, K. K; Jayashree Roy; Duorah, K (Kyivskyi Universytet, 2012-11)
    In this paper, we present the spectral energy distributions (SEDs) of 40 massive young stellar objects (YSOs), detected from the NIR imaging survey carried out by Varricatt et al. 2010 and estimated their ages and masses. ...
  • Study of Young Stellar Objects and Associated Filamentary Structures in the Inner Galaxy 
    Bhavya, B; Subramaniam, A; Kuriakose, V. C (Oxford University Press on behalf of the Royal Astronomical Society, 2013-10-11)
    Young stellar objects in the inner Galactic region 10° < l < 15° and −1° < b < 1° were studied using GLIMPSE images and the GLIMPSE data catalogue. A total of 1107 Class I and 1566 Class II sources were identified in this ...
  • VLTI-AMBER velocity-resolved aperture-synthesis imaging of η· Carinae with a spectral resolution of 12 000 
    Weigelt, G; Hofmann, K. H; Schertl, D; Clementel, N; Corcoran, M. F; Damineli, A; De Wit, W. J; Grellmann, R; Groh, J; Guieu, S; Gull, T; Heininger, M; Hillier, D. J; Hummel, C.

D; Rivinius, T; Scholler, M; Teodoro, M; Wittkowski, M (EDP Sciences, 2016-10)
    Context. The mass loss from massive stars is not understood well. η Carinae is a unique object for studying the massive stellar wind during the luminous blue variable phase. It is also an eccentric binary with a period of ...
