Properties of M31. IV: Candidate Luminous Blue Variables from PAndromeda
C. -H. Lee, S. Seitz, M. Kodric +16
We perform a study on the optical and infrared photometric properties of known luminous blue variables (LBVs) in M31 using the sample of LBV candidates from the Local Group Galaxy…
Characterization of the Praesepe Star Cluster by Photometry and Proper Motions with 2MASS, PPMXL, and Pan-STARRS
P. F. Wang, W. P. Chen, C. C. Lin +31
Membership identification is the first step to determine the properties of a star cluster. Low-mass members in particular could be used to trace the dynamical history, such as mass…
Detection of an outburst one year prior to the explosion of SN 2011ht
M. Fraser, M. Magee, R. Kotak +18
Using imaging from the Pan-STARRS1 survey, we identify a precursor outburst at epochs 287 and 170 days prior to the reported explosion of the purported Type IIn supernova (SN) 2011…
Four new T dwarfs identified in PanSTARRS 1 commissioning data
Niall R. Deacon, Michael C. Liu, Eugene A. Magnier +14
A complete well-defined sample of ultracool dwarfs is one of the key science programs of the Pan-STARRS 1 optical survey telescope (PS1). Here we combine PS1 commissioning data wit…
A Search for High Proper Motion T Dwarfs with Pan-STARRS1 + 2MASS + WISE
Michael C. Liu, Niall R. Deacon, Eugene A. Magnier +13
We have searched ~8200 sq. degs for high proper motion (~0.5-2.7"/year) T dwarfs by combining first-epoch data from the Pan-STARRS1 (PS1) 3-Pi Survey, the 2MASS All-Sky Point Sourc…
Displaying the Heterogeneity of the SN 2002cx-like Subclass of Type Ia Supernovae with Observations of the Pan-STARRS-1 Discovered SN2009ku
G. Narayan, R. J. Foley, E. Berger +22
SN2009ku, discovered by Pan-STARRS-1, is a Type Ia supernova (SNIa), and a member of the distinct SN2002cx-like class of SNeIa. Its light curves are similar to the prototypical SN2…
