The Plan for Transient Follow-up Observations with Maidanak 1.5m Telescope

1. The Plan for Transient Follow-up Observations with Maidanak 1.5m Telescope • Kuiyun Huang (ASIAA), Yuji Urata (NCU) • Peikang Tsai (NCU), Youichi Ohyama (ASIAA), • and Induk Lee (NCU)

2. Discovery of New Transients

3. SCP06F6 Barbary et al.

4. Repeating Survey Programs • MAXI (Monitor of All-sky X-ray Imager) -- cover 0.5-30 keV -- Scan the 80%-95% sky every 92 minutes. • PTF (Palomar Transient Factory) -- 1.28m telescope with FOV~7.78 deg2 -- 5 days cadence (40%), 0.5 day cadence (41%) -- cover 1000 deg2/night -- g’, r’ filters • Pan-STARRS -- 1.8m telescope with FOV~ 7 deg2 -- 3 pi survey with 7 days cadence -- cover 60000 deg2/night -- g’,r’,I’,z’ filters

5. Rau et al. 2009

6. Objects we plan to study • Core-Collapse supernovae (Ib,Ic, and II) • X-ray flashes discovered by the Swift/XRT and the MAXI (e.g. 2008D) 3. Optical transients discovered by PS1 and PTF 4. X-ray transients discovered by MAXI

7. Our Strategies A. Supernovae -- Long term monitoring (days to year) -- Multi-band observations -- Cadence : 1-2 days or longer coverage for each SN B. X-ray flashes -- Need quick response -- High time resolution monitoring , multi-band -- Cadence : 1-5 days after the discovery C. Transients found by PS1 and MAXI -- long term monitoring (days to months) -- multi-band monitoring -- Cadence : observe everyday for selected targets

8. Scientific topics • Investigate the connection between GRBs and supernovae • Systematic study on physical parameters of CCSNe( e.g. distribution of Ni mass, kinetic energy of the explosions) • 3. Make CCSNe photometric templates for investigating high-z SNe. • 4. Identify optical counterparts for x-ray transients. • 5. Study temporal evolution of new types of transients.

9. Experience from GRB follow-up

10. The EAFON results • 1. More than 22 refereed papers were published • 2. Circulated more than 110 GCN Circular. • 3. Four students got PHD with EAFON data.

11. We need similar network for photometric and spectroscopic observations • Photometric program • -- Lulin 1-m telescope (ToO, 2010 Feb.) • -- Maidanak 1.5m telescope (planning) • Spectroscopic program • -- BOAO 1.8m telescope (PI program, 2010 Jan.) • -- Xinglong 2m telescope (planning)

12. With Maidanak 1.5m telescope • Stable weather (especially in summer) and good seeing. • Good image quality (Maidanak1.5m+SNUCCD, pix =0.266”, Lulin 1m+PICCD, pix ~ 0.56”) • High-QE in U (~50%) and I (~90%) filters • Service mode

13. A new black hole candidate :XTEJ1752-223

14. Lulin 1m + Maidanak 1.5m A. Supernovae -- Long term monitoring (days to year) -- Multi-band observations -- Cadence : 1-2 days or longer coverage for each SN B. X-ray flashes -- Need quick response -- High time resolution monitoring , multi-band -- Cadence : 1-5 days after the discovery C. Transients found by PS1 and MAXI -- long term monitoring (days to months) -- multi-band monitoring -- Cadence : observe everyday for selected targets

15. SN2009kf discovered by PS1

16. Summary • We plan to study temporal evolution of • transients with small telescopes. • With experience on EAFON, we could • build similar network for transient study. • The program started with Lulin 1-m this year. • Our next step is building same program with Maidanak 1.5 m telescope.
