A new edition of the HITEMP database has now been placed on the
anonymous ftp site at our lab. This new edition is described in the
article "HITEMP, the high-temperature molecular spectroscopic
database," L.S. Rothman, I.E. Gordon, R.J. Barber, H. Dothe,
R.R. Gamache, A. Goldman, V. Perevalov, S.A. Tashkun, and J. Tennyson,
J. Quant. Spectrosc. and Rad. Transfer 111, 2139-2150 (2010). The new
HITEMP replaces the earlier edition ("HITRAN, HAWKS and HITEMP
High-Temperature Molecular Database," L.S. Rothman, R.B. Wattson,
R.R. Gamache, J. Schroeder, and A. McCann, Proc. Soc. Photo Optical
Instrumentation Engineers 2471, 105-111 (1995)). To access the HITEMP data:

We are happy to announce the release of the NASA Ames PAH IR
Spectroscopic Database and the launch of the accompanying website at
http://www.astrochem.org/pahdb. The paper that describes the database
and site has been published in the August issue of the Astrophysical
Journal Supplement Series (http://iopscience.iop.org/0067-0049/189/2/341/).

"Detection of C60 and C70 in a Young Planetary Nebula",
Abstract: In the last decades, a number of molecules and diverse dust features have been identified by astronomical observations in various environments. Most of the dust that determines the physical and chemical characteristics of the interstellar medium (ISM) is formed in the outflows of asymptotic giant branch (AGB) stars and is further processed when these objects become planetary nebulae (PNe). Here, we report on the environment of Tc 1, a peculiar PN whose infrared spectrum shows emission from cold and neutral C60 and C70. The two molecules amount to a few percent of the available cosmic carbon in this region, showing that if the conditions are right, fullerenes can and do form efficiently in space.

The refereeing process for the HIFI First Result special issue of A & A will conclude on July 31, 2010. As of this writing, a large number of papers have already been accepted and are available through Astroph. Together, these papers give a good impression of the versatility of HIFI and the expected breadth of HIFI's impact on astrophysics and astrochemistry. We want to alert you to the website, http://hifi.strw.leidenuniv.nl/, where we collect these papers and provide relevant links to the teams webpages. As a service to the community, we will add HIFI papers, as they are accepted for publication, to this page throughout the mission. So, you might want to bookmark this page as an easy entry point for HIFI results.
In addition, we hope that these papers may inspire you to submit a proposal in response to the Herschel Open Time Announcement of Opportunity using HIFI (http://herschel.esac.esa.int/AO_Introduction.shtml), which are due on July 22nd, 2010.
