  • Classical Cepheids and the local chemical inhomogeneities in the galactic disc 
    Giridhar, S (1986-06)
    Places of formation have been derived for a sample of 23 Cepheids with well-determined atmospheric abundances in an attempt to study the chemical inhomogeneities in the local interstellar medium. The abundance data available ...
  • Distribution of stars perpendicular to the plane of the Galaxy 
    Chatterjee, S (Indian Academy of Sciences, 1991-12)
    A detailed calculation is given of the distribution of mass above the Galactic plane for any arbitrary mass distribution and velocity distribution. It is shown that an analytic expression can be found for the gravitational ...
  • Integrated parameters of open clusters 
    Pandey, A. K; Bhatt, B. C; Mahra, H. S; Sagar, R (Royal Astronomical Society, 1989-01)
    Integrated magnitudes and colors of population I synthetic clusters have been derived using theoretical evolutionary tracks and an age-dependednt initial mass function. A comparison of the theoretically obtained integrated ...
  • Misaligned Jets from Sgr A* and the Origin of Fermi/eROSITA Bubbles 
    Sarkar, Kartick C; Mondal, Santanu; Sharma, Prateek; Piran, Tsvi (American Astronomical Society, 2023-07-01)
    One of the leading explanations for the origin of Fermi Bubbles is past jet activity in the Galactic center supermassive black hole Sgr A*. The claimed jets are often assumed to be perpendicular to the Galactic plane. ...
  • Nucleus of NGC 2903 
    Prabhu, T. P (D.Reidel Publishing Co.,, 1980-04)
    The nucleus of NGC 2903 is identified on near infrared photographs. The energy distribution of this nucleus in the visual region of the spectrum is estimated from available observations. The continuum compares well with ...
  • UOCS-IX. AstroSat/UVIT Study of the Open Cluster NGC 2818: Blue Stragglers, Yellow Stragglers, Planetary Nebula, and their Membership 
    Sharmila Rani; Pandey, G; Subramaniam, A; Kameswara Rao, N (American Astronomical Society, 2023-03-01)
    We present the first far-UV (FUV) imaging results of the intermediate-age Galactic open cluster NGC 2818 that has a planetary nebula (PN) within the field using images taken from the Ultra Violet Imaging Telescope ...
  • Zodiacal light and the false dawn 
    Vayada, Nilesh; Talwar, Ajay (NASA, 2012-01-16)
    Explanation: Is it dawn or false dawn? During certain times of the year, the horizon near the rising Sun will begin to glow unusually early. This early glow does not originate directly from the Sun, but rather from sunlight ...
