Saberi, M., Javadi, A., van Loon, J. T., & Khosroshahi, H. (2015). Detecting Long Period Variables in M 33 Using UKIRT-WFCAM Images. In Vol. 497 – Why Galaxies Care about AGB Stars III: A Closer Look in Space and Time (497)

We have used the UK InfraRed Telescope (UKIRT) to conduct a near-IR monitoring campaign to search for variable stars in the Local Group spiral galaxy M 33. Most of the 4643 detected variables appear to be Asymptotic Giant Branch (AGB) stars.

DUST in Nearby Galaxies with Spitzer (DUSTINGS): An Infrared Census of Extreme AGB Stars in Nearby Dwarf Galaxies (2015)
Conference Proceeding
Boyer, M. L., McQuinn, K. . B. . W., Barmby, P., Bonanos, A. . Z., Gehrz, R. . D., Gordon, K. . D., …Zijlstra, A. . A. (2015). DUST in Nearby Galaxies with Spitzer (DUSTINGS): An Infrared Census of Extreme AGB Stars in Nearby Dwarf Galaxies. In 497, Why Galaxies Care about AGB Stars III: A Closer Look in Space and Time

Nearby resolved dwarf galaxies provide excellent opportunities for studying the dust-producing late stages of stellar evolution. DUSTiNGS (DUST in Nearby Galaxies with Spitzer) is a 3.6- and 4.5-μm imaging survey of 50 dwarf galaxies within 1.5 Mpc....

Young Stellar Objects in the Magellanic Clouds: Herschel Spectroscopy First Results (2015)
Conference Proceeding
Oliveira, J. M., van Loon, J. T., & Sewiło, M. (2015). Young Stellar Objects in the Magellanic Clouds: Herschel Spectroscopy First Results. . https://doi.org/10.1017/s1743921316008231

We present preliminary results from spectroscopy obtained with PACS and SPIRE onboard the Herschel Space Observatory of a sample of massive Young Stellar Objects in the Magellanic Clouds. We analyse key gas-phase cooling species (OI], [CII], H2O, CO,... Read More about Young Stellar Objects in the Magellanic Clouds: Herschel Spectroscopy First Results.

Young stars and their circumstellar disks in the Sigma Orionis cluster (2004)
Conference Proceeding
M. Oliveira, J., D. Jeffries, R., Th. van Loon, J., & J. Kenyon, M. (2004). Young stars and their circumstellar disks in the Sigma Orionis cluster. In Open Issues in Local Star Formation (55–62). https://doi.org/10.1007/1-4020-2600-5_6

The sigma Orionis cluster is a young association evolving under the disruptive influence of its massive O-star namesake. We are analysing this cluster as part of a program to characterise the influence of O-stars on the early stages of stellar evolut...
