The Gas-Rich Circumbinary Disk of HR 4049. II: A Detailed Study of the Near-Infrared Spectrum
Sarah E. Malek, Jan Cami
HR 4049 is a peculiar evolved binary which is surrounded by a circumbinary disk. Mid-infrared observations show that the disk is rich in molecular gas and radially extended. To stu…
The Gas-Rich Circumbinary Disk of HR 4049 I: A Detailed Study of the Mid-Infrared Spectrum
Sarah E. Malek, Jan Cami
We present a detailed analysis of the mid-infrared spectrum of the peculiar evolved object HR 4049. The full Spitzer-IRS high-resolution spectrum shows a wealth of emission with pr…
Fullerenes in circumstellar and interstellar environments
Jan Cami
In recent years, the fullerene species C60 (and to a lesser extent also C70) has been reported in the mid-IR spectra of various astronomical objects. Cosmic fullerenes form in the…
The Rich Circumstellar Chemistry of SMP LMC 11
Sarah E. Malek, Jan Cami, Jeronimo Bernard-Salas
Carbon-rich evolved stars from the asymptotic giant branch to the planetary nebula phase are characterized by a rich and complex carbon chemistry in their circumstellar envelopes.…
Fullerenes in circumstellar and interstellar environments
Jan Cami, Jeronimo Bernard-Salas, Els Peeters +1
We recently identified several emission bands in the Spitzer-IRS spectrum of the unusual planetary nebula Tc 1 with the infrared active vibrational modes of the neutral fullerene s…
