International Conference on Interstellar Dust, Molecules and Chemistry

Permanent URI for this collectionhttp://localhost:4000/handle/11007/143

The interstellar medium (ISM) consists of a mixture of ions, atoms, molecules, dust grains, cosmic rays, and (galactic) magnetic fields. Thus it is a treasure trove for the study of a wide variety of physical phenomenon. The ISM also plays a crucial role in star and planet formation. The interplay between stars and the ISM determines the lifespan of active star formation and evolution. Recent advances in observational, laboratory, theoretical studies have opened up several avenues of work, made attractive by the possibilities of diverse interdisciplinary interactions. The conference intends to provide platform for expert discussions and presentations with ample opportunities for young and motivated students and researchers to interact and to take up challenging problems in this field. Broad Topics: i) ISM Overview - Constituents, Observational diagnostics ii) Dust in ISM - Composition, Starlight extinction - observations & models iii) ISM Molecules and Spectroscopy iv) Star Formation - The Role of the ISM v) Dust and molecules in external galaxies vi) Laboratory Astrophysics and Astrochemistry vii) Quantum Chemistry

    Compolation of interstellar lines
    (2011-11-22) Preethi, K.; Gudennavar, S. B.; Bubbly, S. G.; et al.
    We have collated absorption line data toward 3014 stars (Fig. 1) in order to create a unified database of interstellar column densities. These data have been taken from a number of different published sources and include many different species and ionizations. The preliminary results from our analysis show a tight relation between N(H) and E(B-V) i.e. [N(H)/E(B-V)=6.12x10²¹]. Similar plots have been obtained with many different species, and their correlations along with the correlation coefficients are presented.
