Decadal pre-explosion activity and circumstellar interaction in a supernova

Ting-Wan Chen, Amar Aryan, Sheng Yang +52

When a massive star explodes as a supernova, crucial information about its immediate environment is lost within hours. Here we report rapid optical observations from Lulin Observat…

The JWST-NIRCam View of Sagittarius C. III. The Extinction Curve

Lucía Bravo Ferres, Francisco Nogueras-Lara, Rainer Schödel +8

Determining the infrared extinction curve towards the Galactic centre is crucial for accurately correcting observed data and deriving the underlying stellar populations. However, e…

Network of velocity-coherent filaments formed by supersonic turbulence in a very-high-velocity HI cloud

Xunchuan Liu, Tie Liu, Pak-Shing Li +17

The warm neutral medium (WNM) was thought to be subsonically/transonically turbulent, and it lacks a network of intertwined filaments that are commonly seen in both molecular cloud…

Core mass function in view of fractal and turbulent filaments and fibers

Xunchuan Liu, Tie Liu, Xiaofeng Mai +5

We propose that the core mass function (CMF) can be driven by filament fragmentation. To model a star-forming system of filaments and fibers, we develop a fractal and turbulent tre…

The first Ka-band (26.1-35 GHz) blind line survey towards Orion KL

Xunchuan Liu, Tie Liu, Zhiqiang Shen +30

We conducted a Ka-band (26.1--35 GHz) line survey towards Orion KL using the TianMa 65-m Radio Telescope (TMRT). It is the first blind line survey in the Ka band, and achieves a se…

Monitoring H Emission from the Wide-orbit Brown-dwarf Companion FU Tau B

Ya-Lin Wu, Yu-Chi Cheng, Li-Ching Huang +5

Monitoring mass accretion onto substellar objects provides insights into the geometry of the accretion flows. We use the Lulin One-meter Telescope to monitor H emission from FU…

Asteroid Spin-Rate Study using the Intermediate Palomar Transient Factory

Chan-Kao Chang, Wing-Huen Ip, Hsing-Wen Lin +10

Two dedicated asteroid rotation-period surveys have been carried out using data taken on January 6-9 and February 20-23 of 2014 by the Intermediate Palomar Transient Factory (iPTF)…

Asteroid lightcurves from the Palomar Transient Factory survey: Rotation periods and phase functions from sparse photometry

Adam Waszczak, Chan-Kao Chang, Eran O. Ofek +10

We fit 54,296 sparsely-sampled asteroid lightcurves in the Palomar Transient Factory to a combined rotation plus phase-function model. Each lightcurve consists of 20+ observations…

VI-Band Follow-Up Observations of Ultra-Long-Period Cepheid Candidates in M31

Chow-Choong Ngeow, Chien-Hsiu Lee, Michael Ting-Chang Yang +7

The ultra-long period Cepheids (ULPCs) are classical Cepheids with pulsation periods exceeding days. The intrinsic brightness of ULPCs are ~1 to ~3 mag brighter than t…

313 new asteroid rotation periods from Palomar Transient Factory observations

Chan-Kao Chang, Wing-Huen Ip, Hsing-Wen Lin +11

A new asteroid rotation period survey have been carried out by using the Palomar Transient Factory (PTF). Twelve consecutive PTF fields, which covered an area of 87 deg in the…

Discovery of Main-Belt Comet P/2006 VW139 by Pan-STARRS1

Henry H. Hsieh, Bin Yang, Nader Haghighipour +39

Main belt asteroid (300163) 2006 VW139 (later designated P/2006 VW139) was discovered to exhibit comet-like activity by the Pan-STARRS1 survey telescope using automated point-sprea…
