The low mass young stellar objects (LM-YSOs) that are still accreting from their disc,
are observationally found to undergo short duration outbursts which are separated by
long quiescent phases. These rare outburst phenomenon observed in LM-YSOs are called FU
Ors and EX Ors. These eruptions of the LM-YSOs are caused by strongly enhanced accretion
from the surrounding disc. FU Ors display outbursts of ~ 4 mag or more and last several
decades, whereas EX Ors show smaller outbursts (∆m ~ 2 - 3 mag) that last from a few
months to a few years and may occur repeatedly. These short timescales, when compared to
the 10^4 - 10^5 formation timescales of the young stars, make these events extremely rare,
and so far, less than a dozen sources have been detected. Spectroscopically, FU Ors have
broad line widths, believed to be due to large rotational velocities. Their spectral
type vary from early type F or G in the optical to later type M in the NIR. The most
realistic models of their spectra are produced by using a strong accretion disc with
lower temperatures at larger radii. The episodic nature of accretion seen in these
LM-YSOs can shed light on several open problems in star formation and accretion disc
theories. In this talk, I will present recent results from our long-term monitoring
observations of a few rare type of eruptive young low mass variables. I will end up my
talk with a brief presentation of current and future observational facilities in India.
