  • Stara -Disk Interactions in Multiband Photometric Monitoring of the Classical T Tauri Star GI Tau 
    Guo, Zhen; Herczeg, Gregory J; Jose, J; Fu, Jianning; Chiang, Po-Shih; Grankin, Konstantin; Michel, R; Yadav, Ram Kesh; Liu, Jinzhong; Chen, Wen-Ping; Li, Gang; Xue, Huifang; Niu, Hubiao; Subramaniam, A; Sharma, Saurabh; Prasert, Nikom; Flores-Fajardo, Nahiely; Castro, Angel; Altamirano, Liliana (IOP Publishing, 2018-01)
    The variability of young stellar objects is mostly driven by star – disk interactions. In long-term photometric monitoring of the accreting T Tauri star GI Tau, we detect extinction events with typical depths ...
  • Stellar Content and Star Formation in Young Clusters Influenced by Massive Stars 
    Jose, J (American Astronomical Society, 2014-09)
    Star Formation (SF) in extreme environment is always challenging and can be significantly different from that in quiet environments. This study presents the comprehensive multi-wavelength (optical, NIR, MIR and radio) ...
  • Stellar contents and star formation in the young open cluster Stock 8 
    Jose, J; Pandey, A. K; Ojha, D. K; Ogura, K; Chen, W. P; Bhatt, B. C; Ghosh, S. K; Mito, H; Maheswar, G; Sharma, S (Blackwell Publishing, 2008-03)
    We present UBVIc CCD photometry of the young open cluster Stock 8 with the aim of studying its basic properties such as the amount of interstellar extinction, distance, age, stellar contents and initial mass function (IMF). ...
  • A study of the starless dark cloud LDN 1570: Distance, dust properties, and magnetic field geometry 
    Eswaraiah, C; Maheswar, G; Pandey, A. K; Jose, J; Ramaprakash, A. N; Bhatt, H. C (EDP Sciences, 2013-08)
    Aims. We aim to map the magnetic field geometry and to study the dust properties of the starless cloud, L1570, using multi-wavelength optical polarimetry and photometry of the stars projected on the cloud. Methods. The ...
  • Type Ia supernova SN 2003du: Optical observations 
    Anupama, G. C; Sahu, D. K; Jose, J (EDP Sciences, 2005-01)
    UBVRI photometry and optical spectra of type Ia supernova SN 2003du obtained at the Indian Astronomical Observatory for nearly a year since discovery are presented. The apparent magnitude at maximum was $B=13.53\pm ...
  • Young stellar population and ongoing star formation in the H ii complex Sh2-252 
    Jose, J; Pandey, A. K; Samal, M. R; Ojha, D. K; Ogura, K; Kim, J. S; Kobayashi, N; Goyal, A; Chauhan, N; Eswaraiah, C (Oxford University Press on behalf of the Royal Astronomical Society, 2013-07-11)
    In this paper, an extensive survey of the star-forming complex Sh2-252 has been undertaken with an aim to explore its hidden young stellar population as well as to understand the structure and star formation history for ...
  • Young stellar population in the star-forming complex Sh2-252 
    Jose, J; Pandey, A. K; Ogura, K; Bhatt, B. C (Astronomical Society of India, 2012)
    We present the preliminary results of our multi-wavelength analyses of the young stellar population associated with the star forming complex Sh2-252. The NIR and MIR data sets from 2MASS and Spitzer-IRAC, MIPS identified ...
  • Young stellar population of bright-rimmed clouds BRC 5, BRC 7 and BRC 39 
    Panwar, N; Chen, W. P; Pandey, A. K; Samal, M. R; Ogura, K; Ojha, D. K; Jose, J; Bhatt, B. C (Oxford University Press on behalf of the Royal Astronomical Society, 2014-09-11)
    Bright-rimmed clouds (BRCs), illuminated and shaped by nearby OB stars, are potential sites of recent/ongoing star formation. Here we present an optical and infrared photometric study of three BRCs: BRC 5, BRC 7 and BRC ...
